Cobalt M35 Drill Bit Set
The XIANFENGHU set contains ten M35 cobalt high-speed steel bits ranging from 1/16" to 13/64". Each bit uses 5% cobalt alloy for improved wear and heat resistance during demanding drilling tasks. The 135° split-point tip reduces walking and starts holes cleanly in hard and soft materials. A plastic storage case keeps the pieces organised and protected.
Suitable for mixed-material work
This set suits tradespeople and DIY users who drill stainless steel, cast iron, copper, aluminium, wood and plastic with a single kit. The jobber-length design fits standard drill chucks for quick changes on site. Buyers needing larger diameters, longer reach or specialised coatings for abrasive composites should look at alternative ranges. The ten-piece count covers common pilot and clearance sizes only.
Ten metric sizes included
The kit supplies 1.5, 2, 2.5, 3, 3.2, 3.5, 4, 4.2, 4.5 and 5 mm bits for fine to medium hole work. The fully ground spiral flutes clear chips quickly, lowering friction and heat buildup during repeated cuts. Capacity ends at 5 mm, so structural steel, thick plate or masonry jobs will require separate tooling. Heat-treated M35 steel extends life across multiple projects.

Questions about this item
What chuck size do I need on my drill to hold the largest 13/64 inch bit in this set?
The largest bit is 13/64 inch, so any drill with a 1/2 inch (13 mm) chuck will accept the full range.
Will the 135° split point on these M35 cobalt bits start cleanly in thin stainless steel without a centre punch?
Yes, the 135° split point is designed to self-centre and reduce walking on hard materials such as stainless steel and cast iron.
How can I confirm the bits are cutting efficiently once I start drilling?
Look for continuous spiral chips and steady feed pressure; the fully ground flutes and double helix design should evacuate swarf quickly and keep the bit running cooler.
