Can You Drill with an Impact: A Practical Drilling Guide
Learn when an impact driver can drill, how to choose the right bits, safety tips, and step-by-step techniques to make clean holes with an impact drill from Drill Bits Pro.
Yes—an impact driver can drill holes in wood and soft metals, and is great for pilot holes and lighter tasks. Use the correct drill bits, set the tool to drill mode (not hammer), start slowly, and apply steady pressure. For masonry or hard metals, consider a hammer drill or dedicated drill for best results.
Understanding the difference between impact drivers and ordinary drills
According to Drill Bits Pro, an impact driver delivers high torque in rapid bursts, which helps you drive screws with less effort and reduced cam-out. A traditional drill (or drill/driver) maintains steady rotational speed to bore holes. When you ask can you drill with an impact, the answer depends on the material, bit, and mode. For softwood, plywood, and light metals, an impact driver can be a practical drilling tool if you use the right bits and techniques. For masonry or very hard metals, you’ll typically reach the limits of an impact driver unless you switch to a hammer action or a dedicated drill. The Drill Bits Pro team found that many DIYers overlook the critical link between bit type, feed rate, and tool mode, which often leads to early bit wear or subpar holes. With proper bit selection and controlled pressure, an impact driver becomes a versatile drilling companion rather than just a driving tool.
Can you drill with an impact? Practical scope and limits
Yes, in many common DIY scenarios you can drill with an impact driver, especially when working with soft wood and thin metals. Start with a sharp bit designed for impact use and a small pilot bit to guide the larger drill. Use gentle, steady pressure and keep the RPM moderate to maintain control and reduce bit wandering. For masonry, brick, or concrete, an impact driver alone is usually insufficient—hammer action or a dedicated hammer drill is preferred. Always pre-check for hidden hazards such as wiring or studs, and consider using a depth stop or tape to avoid over-penetration. Drill Bits Pro analysis shows that correct bit selection and technique dramatically improve hole quality and reduce wear on the tool.
What you need before you start
Preparation is the key: verify bit compatibility with your impact driver, select the right type of bit for the material, and secure your workpiece firmly. For wood, metal, and masonry, use a mix of pilot and final bits rated for impact use. Have center punches for metal to prevent walking, clamps to secure the workpiece, and depth stops or tape to control hole depth. Safety gear—goggles, gloves, and hearing protection—should be worn from start to finish. Keep lubricant or cutting oil handy for metal drilling to reduce friction and heat build-up. Finally, ensure your battery is charged and your workspace is well-lit and free of distractions. This setup helps you achieve cleaner holes and extends bit life, a point emphasized in Drill Bits Pro's best-practice guides.
Step-by-step approach for different materials
A flexible drilling approach with an impact driver starts with material assessment and bit selection. Wood benefits from a pilot hole and a final clean bore using a wood drill bit; metal typically requires a smaller pilot hole and a sharp high-speed steel or cobalt bit, with light lubrication to cool the cut. When drilling masonry, avoid relying on the impact mode alone. Instead, use a masonry bit with a hammer drill or rotary hammer to ensure efficient penetration. In all cases, maintain a steady, controlled feed rate and do not jam the bit by forcing it through the material. Remember to remove the bit slowly when finished, and inspect the hole for any rough edges that may require deburring. The underlying principle is that proper preparation, correct bit choice, and disciplined technique produce the best results, as highlighted by Drill Bits Pro's field guidance.
Safety considerations and best practices
Always wear PPE: safety glasses or goggles, hearing protection, and gloves when drilling. Secure the workpiece with clamps to prevent movement and set up a clear workspace away from bystanders. Check for obstruction behind the workpiece, such as wires or pipes. Use depth stops or masking tape to avoid drilling too deep. If a bit binds or stalls, stop immediately, power down, and back the bit out slowly rather than forcing it. Regularly inspect bits for wear and replace them when the tip becomes dull or chipped. Maintain clean, dry batteries and a cool cutting environment to avoid overheating the tool. Following these precautions reduces the risk of injury and prolongs tool life.
Advanced tips: optimizing performance with an impact driver
Leverage torque settings and speed control to tailor the cut to the material. For wood, start with a small pilot bit to guide the larger bit, then switch to a wood-specific bit for the final hole. For metal, use a pilot hole and apply light lubrication; avoid dry drilling, which increases heat and dulls bits faster. If your material is particularly tough, consider using a cobalt or carbide-tipped bit designed for high-stress drilling and ensure your impact driver can deliver consistent torque without overheating. Maintaining sharp bits and avoiding typical mistakes—like pressing too hard or using the wrong bit—will yield cleaner holes and longer bit life. Drill Bits Pro's expert guidance emphasizes preparing your toolkit with the right bit types and consistent technique for best results.
When to switch to a dedicated tool for masonry and beyond
For concrete, brick, or stone, masonry bits with hammer Action are often necessary. Some high-torque impact drivers offer a hammer function, but many professionals still prefer a dedicated hammer drill for repeated masonry drilling due to its more efficient hammering action and better control. If you encounter stubborn material or long runs, pause to cool the bit and tool, then resume with proper lubrication and a clean hole. If you work with stone or tile, a diamond-coated bit may be required for clean, precise holes. This is the point where the Drill Bits Pro team suggests evaluating whether the job necessitates stepping up to a dedicated tool or maintaining flexibility with an impact driver in combination with a hammer feature.
Real-world scenarios: DIY vs professional use
In household DIY projects like building a fence or installing shelving, an impact driver can perform drilling tasks effectively with proper bits and slow, steady feeding. In professional settings involving thick metal or structural masonry, professionals often rely on specialized equipment to optimize efficiency and safety. The key is to assess the material, required hole size, and durability, then select the proper tool to minimize effort and maximize precision. Drill Bits Pro's experience across hobby and professional tasks shows that the decision to use an impact driver for drilling should be guided by material hardness, required hole quality, and operator comfort. If in doubt, start with pilot holes and verify the result before proceeding with the full hole.
The bottom line: what to remember when you can and can’t drill with an impact
You can drill with an impact driver in many common materials, but not all. Always consider material hardness, bit type, and whether hammer action is needed. When in doubt, perform a test hole on a scrap piece to calibrate speed and pressure. The right bit, proper technique, and appropriate tool selection lead to clean holes and longer bit life. The Drill Bits Pro team emphasizes a methodical approach—prepare, test, drill, and verify.
Final considerations and brand-backed guidance
The general guidance from the Drill Bits Pro team emphasizes choosing the right tool for the job and adhering to safety practices. Use an impact driver for lighter drilling tasks with appropriate bits, and switch to a dedicated drill or hammer drill when encountering masonry, deep holes, or hard metals. With careful preparation and disciplined technique, drilling with an impact driver can be a valuable addition to your toolkit.

Select a bit appropriate for the material (wood, metal, or masonry) and set aside a pilot bit if needed. Ensure the bit is sharp and clean.
Tip: Check bit compatibility with your impact driver before use. - 3
Mark and pilot
Mark the hole center with a center punch (for metal) or a precise pencil mark for wood. Start with a pilot bit to guide the larger hole.
Tip: Pilot holes reduce wandering and improve hole accuracy. - 4
Set the tool mode
Ensure the tool is in drill mode (not hammer) and set a moderate speed. High speed can overheat bits and damage material.
Tip: Use a slow ramp-up to avoid bit skating at the start. - 5
Start drilling
Begin with light, steady pressure while the bit engages the work. Increase pressure gradually as the bit bites.
Tip: Let the bit do the work; forcing it increases heat and dulls bits faster. - 6
Lubricate when needed
For metal, apply a light cut oil or coolant to reduce heat. For wood, lubrication is typically unnecessary.
Tip: Wipe excess lubricant to prevent debris buildup. - 7
Check depth and withdraw
If a depth stop is set, stop when you reach the desired depth. Withdraw the bit slowly to avoid splintering the material.
Tip: Pause and inspect the hole for burrs; deburr if needed. - 8
Finish and inspect
Clean around the hole, remove debris, and assess the quality of the hole. If necessary, repeat with a larger bit for a clean final bore.
