Drill bit pack AWTools AW42070 — 10 pcs

The AWTools AW42070 — 10 pcs drill bit pack contains ten precision-ground HSS-Co (high-speed steel with 5% cobalt) twist drill bits supplied in a compact case. Each bit features two cutting edges and a centering point with a 135° point angle for reduced walking and accurate hole starts. Designed as replacement or consumable drill bits, this multi-pack is intended for workshops, construction sites and DIY use where multiple identical bits are required for repetitive drilling and maintenance work.

Advantages

HSS-Co material with 5% cobalt increases heat resistance and wear life compared with standard high-speed steel, allowing longer runs under higher cutting temperatures. The precision-ground two-cutting-edge geometry ensures consistent chip formation and smoother drilling action. The 135° point angle improves centering and reduces the need for pre-piloting on many materials. Supplied in a case, the set keeps bits organized and protected between uses.

Suitable for

• Drilling alloyed and unalloyed steels
• Working with grey cast iron
• Drilling non-ferrous metals such as aluminium and brass
• Creating holes in plastics
• Workshops, maintenance and repetitive production tasks

How to use

Select the appropriate drill diameter from the pack and secure the bit in the drill chuck ensuring tight and concentric clamping. Use recommended cutting speeds and feed rates for the material being drilled, apply cutting fluid when working with steels and alloyed metals to extend tool life, and use steady pressure to let the bit cut without excessive force. Retract periodically to clear chips when drilling deep holes and allow the bit to cool between prolonged runs.

Usage recommendations

For best results on alloyed steels and hard materials, use lower cutting speeds and consistent cutting fluid. When drilling plastics, use higher spindle speed with light feed and consider backing the workpiece to avoid chipping. Store bits in the supplied case to protect cutting edges and keep them dry to prevent corrosion.
