Drill bit Irwin spiral hex shank for wood 8 mm model 10502741

Irwin spiral hex shank wood drill bit, 8 mm, model 10502741, is designed for drilling accurate, clean holes in softwoods and hardwoods. The spiral flute geometry evacuates chips efficiently to maintain cutting performance and reduce clogging, while the hexagonal shank ensures a secure grip in standard chucks and quick-change adapters. This bit is suitable for use with handheld drills and impact drivers commonly used in woodworking and carpentry.

Advantages

The spiral flute design provides efficient chip removal and consistent drilling progress, minimizing tear-out on entry and exit. The hex shank offers positive engagement in chucks and rapid-fit holders, reducing slippage and improving torque transfer. Hardened cutting edges maintain sharpness for repeated use in a variety of wood types, and the straight, accurate flute profile helps produce clean, round holes with minimal finishing.

Suitable for

• Drilling holes in softwood and hardwood for furniture and joinery
• Installing dowels, fasteners and connectors in carpentry
• On-site drilling with corded or cordless handheld drills
• Quick-change operations using hex-shank adapters or impact drivers

Key specifications

• Diameter: 8 mm
• Shank type: Hexagonal shank for secure chuck and quick-change compatibility
• Flute: Spiral flute for efficient chip evacuation
• Intended material: Softwood and hardwood
• Typical use: Handheld drills and impact drivers in woodworking and carpentry

How to use

Choose the correct drilling speed for the wood type and secure the workpiece to prevent movement. Insert the hex shank into the chuck or quick-change adapter and tighten firmly. Start drilling at a moderate speed to establish a clean entry, apply steady axial pressure and allow the spiral flute to clear chips; back the bit out periodically on deep holes to remove accumulated sawdust. For best results, finish holes with light sanding if a perfectly smooth surface is required.

Usage recommendations

Use appropriate personal protective equipment, such as eye protection and hearing protection. Match drill speed and feed pressure to the wood species to avoid burning or excessive tear-out. For precise depth control, use a depth stop or mark the bit with tape. Keep the bit clean and sharpen or replace it when cutting performance declines.
