10pcs 3.175mm Tungsten Steel Milling Cutter Bits End Mills for Drill Hole
Shank diameter:3.175 mm
Material:Hard alloy (tungsten steel)
High hardness, high wear resistance, high strength, resistance to bending, resistance to wreck.
Bit chip space is large: small chip resistance, smooth, little heater of drill, reduce pollution of drill;
Extraordinary cutting edge sharpness: As a result of nanotechnology and advanced grinding technology, bit more sharp cutting edge than before, can reduce the cutting force, reduce the broken drill rate, improve the hole wall quality;
Cutting edge strictly symmetrical: beneficial and efficient cutting, avoid offset drilling.
2 x set (10pcs) Milling Tools
