Drill bit AWTools AW20550 — model AW20550, general-purpose metal/wood drilling

AWTools AW20550 is a general-purpose drill bit designed for use with handheld and stationary drills. Made of HSS M2 high speed steel, the AW20550 combines drilling and tapping into a single tool for straightforward hole making, repair and assembly work in materials such as wood, soft metals and plastics. The fully ground surface and self-centering tip provide accurate starts and consistent hole geometry while the one-step drilling and tapping feature reduces working time and simplifies operation.

Advantages

The AWTools AW20550 offers a fully ground flute profile for improved precision and faster cutting action. Its HSS M2 construction provides wear resistance and thermal stability for repeated use. A self-centering tip eliminates the need for pre-punching, and optimized chip removal reduces clogging for smoother drilling and tapping. The tool produces precise metric right-hand threads suitable for both machine and manual threading.

Suitable for

• Drilling and tapping holes in soft metals such as aluminum and copper
• General woodworking where combined drilling and threading is required
• Plastic components requiring threaded inserts or through-holes
• Repair, maintenance and assembly tasks in DIY and light industrial settings

Key specifications

• Material: HSS M2 (high speed steel)
• Design: fully ground surface with self-centering tip
• Function: one-step drilling and tapping for metric right-hand threads
• Chip evacuation: optimized flute geometry for smooth chip removal
• Application: suitable for machine and manual threading
• Compatible with: standard drill chucks for handheld and stationary drills

How to use

Secure the workpiece and select an appropriate rotation speed for the material: lower speeds for harder metals, moderate speeds for aluminum and plastics, and higher speeds for wood. Fit the AWTools AW20550 into a standard drill chuck and ensure it is clamped firmly. Align the self-centering tip at the intended location and apply steady feed pressure; the combined drilling and tapping action will form the hole and thread in a single pass. Withdraw the drill periodically to clear chips when working on deeper holes.

Usage recommendations

Use cutting fluid or appropriate coolant when working with metals to extend tool life and improve chip evacuation. For best results, start with a pilot hole if working on thin or flexible materials, and always secure small parts with clamps or a vise to prevent movement during drilling and tapping.
