Drill bit AWTools AW41200 — pack of 5 pieces

AWTools AW41200 — pack of 5 drill bits made of HSS-G high-speed steel, precision ground and double-sided. Each bit features a 118° point angle for improved centring and smooth penetration. The set is supplied in a case and is intended as replacement or spare bits for general drilling tasks in workshop and construction environments. Compatible with drills that accept standard straight-shank bits, these AWTools drill bits are suitable for a variety of materials including alloyed and unalloyed steel, grey cast iron, non‑ferrous metals and plastics.

Advantages

The bits are manufactured from HSS-G high-speed steel and precision ground to ensure consistent cutting geometry and wear resistance. A double-sided design extends usable life by allowing regrinding or flipping, while the 118° point angle improves centring and reduces walking at drill start. Supplied in a compact case, the pack of five allows quick replacement on the job and organised storage.

Suitable for

• Drilling alloyed and unalloyed steel
• Drilling grey cast iron
• Drilling non-ferrous metals (aluminium, brass, copper)
• Drilling plastics and composite materials
• Workshop and construction general-purpose drilling

Key specifications

• Material: HSS-G high-speed steel
• Quantity: 5 pieces per pack
• Tip geometry: 118° point angle
• Finish: precision ground, double-sided
• Shank type: straight shank (standard)
• Packaging: supplied in a protective case

How to use

Select a drill and chuck compatible with standard straight-shank bits, insert the chosen AWTools AW41200 bit and tighten the chuck securely. Use appropriate cutting speed and lubrication depending on the material: higher speeds for non-ferrous metals and plastics, lower speeds for hardened steels. Apply steady feed pressure, avoid excessive force that can cause bit overheating or breakage, and clear chips regularly to maintain cutting efficiency. When one cutting edge becomes dull, rotate or regrind the double-sided bit if appropriate, or replace it with another from the pack.

Usage recommendations

Use cutting fluid or coolant when drilling steels and cast iron to prolong tool life. For plastics, use slower spindle speeds and minimal feed to prevent melting. Store the bits in the provided case to protect edges and keep sets organised.
