Description
1. Drill Bits Size: 3mm/3.2mm/3.5mm/4mm/4.2mm/4.5mm/5mm/5.2mm/5.5mm
2. Quantity/Package: 10Pcs in a Package.
3. Material: HSS Cobalt High Speed Steel is the best material for improving performance and drilling life when drilling and cutting harder matels, such as stainless steel and other metal.
4. Double End Cutitng Point: The 2 cutting point of one single drill bit, when one cutting point is used bored and the other cutting end can be used, as another new drill bit.
5. Function: Cobalt drill bits are more expensive than other drill bits, but if you regularly drilling through metal, they are a good investment since they tend to last longer.
6. Split Point 135 Deg.Cutting Point: No center punch is needed-- the aggrevsive 135 Deg. Split Point quick-cut points are self-centering and penetrate quickly with less pressure. Will not "walk" or"wander".
7. Manufacturing Process: Precision ground points, flutes, body, clearance and drill diameter for ultimate in accuracy and peroformance. Ground flutes provides fast chips removal to maximize accuracy and efficiently along the full working surface of the bit.
8. Chucking Shank: Round shank allow use with a wide variety of tool holding systems.
