Drill bit AWTools AW49657, 40 g handheld metal/wood drilling accessory

AWTools AW49657 drill bit is a compact 40 g handheld accessory made of HSS high-speed steel for drilling metal and wood. Designed for use with standard drills and compatible with bi-metal hole saw adapters, this bit features a self-centering tip that reduces slipping and helps start holes precisely. Its small, lightweight form makes it suitable for repair, assembly and light construction or DIY tasks where a reliable, general-purpose bit is required.

Advantages

The HSS high-speed steel construction provides wear resistance and sustained cutting performance when drilling common metals and wood. The self-centering tip minimizes wandering at the start of drilling, improving accuracy and reducing the need for pilot holes. Compatibility with bi-metal hole saw adapters increases versatility by allowing the bit to act as a pilot for hole saws. Its low weight and compact size make it easy to handle and store, and it is suitable for use in confined spaces and handheld operations.

Suitable for

• General metal drilling tasks on thin sheets and profiles
• Wood drilling for assembly and small carpentry work
• Pilot drilling for bi-metal hole saws and cutting attachments
• Repair, maintenance and DIY projects requiring a compact bit

Key specifications

• Material: HSS (high-speed steel)
• Weight: 40 g
• Tip type: self-centering (reduced slipping, improved start)
• Compatibility: suitable for use with standard handheld drills and bi-metal hole saw adapters
• Application: metal and wood drilling, pilot drilling for hole saws

How to use

Secure the drill bit in the chuck of a compatible handheld drill, ensuring it is tightened centrally to prevent runout. For best results on metal, clamp the workpiece and mark the drilling point; use cutting fluid on thicker or harder metals. For wood, ensure the surface is stable and start drilling at low speed to let the self-centering tip engage, then increase speed as appropriate. When used as a pilot for a bi-metal hole saw, align the bit with the intended center of the hole and run the hole saw at recommended speeds while applying steady, moderate pressure.

Usage recommendations

Wear appropriate eye and hand protection. Use steady, controlled pressure and avoid excessive axial force that can overload the bit. For prolonged drilling in metal, periodically withdraw the bit to clear chips and apply cutting fluid to extend tool life. Store the bit dry and protected from impact to preserve the cutting edge.
