Drill Bit DeWalt 10 mm cylindrical (DT6686-QZ) for metal and general drilling

DeWalt 10 mm cylindrical drill bit DT6686-QZ is designed for general-purpose drilling in metal and other common materials. The straight (cylindrical) shank fits standard drill chucks and allows secure clamping for workshop and construction use. With a 10 mm cutting diameter, this drill bit covers routine holemaking tasks where a reliable, single-diameter tool is required.

Advantages

The cylindrical shank ensures compatibility with a wide range of drill chucks and quick, stable mounting. The 10 mm cutting diameter provides a balance between precision and strength for through-holes and pilot holes. Manufactured by a reputable brand, this bit offers consistent geometry for predictable drilling performance and easier control when working with metals and general materials.

Suitable for

• Drilling through mild steel and sheet metal
• Routine workshop and construction holemaking
• Pilot holes for fasteners and bolts
• General-purpose metalworking and fabrication tasks

Key specifications

• Cutting diameter: 10 mm
• Shank type: cylindrical / straight shank for standard chucks
• Intended materials: metal and general-purpose materials
• Design: single-flute geometry for general drilling performance

How to use

Secure the drill bit in a compatible chuck, ensuring the shank is inserted fully and tightened. Select an appropriate drill speed and cutting fluid when drilling metal to reduce heat and wear. Start drilling with steady pressure, keeping the drill perpendicular to the workpiece to maintain hole accuracy. Withdraw the bit periodically for chip clearance when drilling deeper holes.

Usage recommendations

Use cutting lubricant for prolonged bit life when working with steel. Match drill speed to material thickness: lower speeds for thicker metal, higher speeds for thinner sheets. Inspect the bit for wear and replace when edges become dull to avoid damaging the workpiece.
