Drill bit AWTools AW41875 — pack of 10

AWTools AW41875 — pack of 10 drill bits supplied in a compact case. Each bit is made from HSS-G M2 high-speed steel, precision ground with two cutting edges and a black oxide finish. The bits feature a 135° centering point for accurate starts and are designed for general drilling tasks in metals and plastics when used with compatible drills.

Advantages

The HSS-G M2 construction provides high wear resistance and reliable edge retention during repeated use. Precision grinding and two cutting edges ensure cleaner holes and reduced chatter. Black oxide treatment improves corrosion resistance and lubrication during cutting, while the 135° centering point reduces walking and lowers the risk of breakage when starting holes.

Suitable for

• Drilling alloyed and unalloyed steel
• Drilling grey cast iron
• Drilling non-ferrous metals such as aluminum and copper
• Drilling plastics and other synthetic materials
• Workshop, industrial and DIY projects requiring multiple identical bits

Key specifications

• Material: HSS-G M2 high-speed steel
• Cutting geometry: two cutting edges, precision ground
• Surface finish: black oxide
• Point angle: 135° centering point
• Pack quantity: 10 pieces in a storage case

How to use

Select a bit size compatible with your drill and the material to be worked. Secure the workpiece, mark the drilling position, and use appropriate clamping. Install the bit into the drill chuck and tighten securely. Start drilling at moderate speed to engage the 135° centering point, then adjust speed according to material (slower for harder metals, faster for softer metals and plastics). Use cutting fluid or lubrication for metal drilling when appropriate, and remove chips regularly to prevent clogging and overheating.

Usage recommendations

For best performance, match drill speed and feed to the material: lower speeds and steady feed for hardened or alloyed steels, higher speeds for non-ferrous metals and plastics. Use light cutting fluid on steels to extend bit life. Store bits in the provided case to protect cutting edges and maintain organization on the job.
