10CPS/Box 0.8mm PCB Plastic Stainless Steel Drilling Bit Tungsten Carbide Engraving Drill BitMicro Mini Set

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 :As a result of nanotechnology and advanced grinding technology, bit more 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.Material:Hard alloy (tungsten steel).Specification: Shank diameter:3.175 mmBlade diameter:0.8mmTotal length:38mmPackage included: 1x set (10pcs) Milling Tools Drill BitsNo need for shaking or reducing friction, capable of withstanding heavy-load operations, making the cutting process smoother

• 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 :As a result of nanotechnology and advanced grinding technology, bit more 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.
• Material:Hard alloy (tungsten steel).
• It is convenient to carry. The drill bit is placed in a plastic box, which makes it easy to store and carry .
