Uxcell 2.35mm C3/K10 Tungsten Carbide Mini Precision Straight Shank Twist Drill Bit

The solid carbide drill bit is made of a micro grain tungsten-cobalt alloy with an average cobalt content of 6%. It has high hardness (HRC92) wear resistance heat resistance high bending strength and resistance to stick. Provides faster cutting speeds than other substrates and is harder but more brittle. Large and spiral chip space design for fast and clean chip removal. Sharp cutting edge provides smooth cutting and no glitches. With good milling and cutting performance carbide ensures high working efficiency. Suitable for precisely drilling materials below HRC45 such as stainless steel alloy steel tool steel carbon steel aluminum alloy plastic wood etc.. Drill metal with high hardness the rotational speed should be slower than normal drilling. Used on machining centers drilling machines CNC lathes CNC engraving and milling machines. Adapt to several kinds of cooling conditions such as oil mist water oil air cooling. Suitable lubricant is conducive to cutting or cooling making cutting easier improving smoothness and dimensional accuracy. Tips: Keep cool and gentle when using. The longer the length of the tool clamped by the chuck the better. Not recommended for use with a hand drill (easy to shake poor stability). Proper use can greatly extend the working life of the straight shank twist drill bits.
