Yougfin Cobalt Drill Bits,M35 High Speed Steel Drill Bit Set with Round Straight Shank,135° Split Point,Double Fluted,15Pcs
- 【M35 HSS+5% Cobalt】：Yougfin drill bits are made of M35 High Speed Steel with 5% Cobalt added, which is much harder than typical HSS and thus suitable for precision drilling in stainless steel and other hard materials. What's more, cobalt blend gives these bits a much longer life
- 【Dual Flutes】:Drill bits are rotary cutting tools that have two cutting edges and two flutes which are grooves formed in the body to provide cutting lips, to permit the removal of chips and to allow coolant or cutting fluid to reach the cutting action
- 【135° Split Point】：These bits have a small point angle of 135° and require less pressure when centering in the material. The point starts drilling at contact, reducing friction, pressure, and heat. The larger the point angle, the higher the contact pressure and the centering in the material requires more pressure
- 【Operation Technique】：When drilling a hole with a cobalt bit, add a drop of oil on the metal to keep the cutting edge cooler as it cuts. You also want to consider placing some wood underneath the steel if possible. This lets you cut cleanly through the material and not strike a surface below which might dull the cutting edge
- 【Application & Tip】：Yougfin Jobber Drill Bit are ideal for sheet metal working and are suitable for cutting non-ferrous metals, plastic, wood board, etc. ***Tip***：Please keep the bit perpendicular to the material during operation to prevent it from breakage.
