Large chip removal space: Small chip resistance, smooth chip removal, drilling heat is small, can reduce drilling contaminated.
Extraordinary cutting edge sharpness: As a result of nanotechnology and advanced grinding technology, the drill cutting edge is sharper than before, can reduce the cutting forces and reduce broken drill rate, improve the hole wall quality;
Based clients application design tool: Drill bit rich varieties to meet different application requirements. All the parameters of the drill bit, such as drill core thickness, core of drilling taper, etc., are carefully designed, effectiveness significantly;
Symmetrical cutting edge: In favor of efficient cutting, avoid offset drilling.
Processing range: PCB, SMT, CNC, mould, plastic, copper, stainless steel and other precision metal parts processing.
Blade diameter: 0.1 to 3.2mm
Shank diameter: 3.175mm
Size: 0.2mm, 0.3mm, 0.4mm, 0.5mm (10pcs are the same size in a box)
Each box of drill bit is the same size.
This drill is used to the engraving machine and high-speed machine bed.
Not suitable for hand-held drill, because hand-held electric drill is unstable and easily broken when drilling!
