1.product description:
Applicable materials: circuit board, epoxy resin, synthetic stone, carbon fiber, hardwood, etc.
Applicable machine tools: advertising engraving machine, woodworking engraving machine, CNC machining center, etc.
Features: High-quality imported tungsten steel hard alloy material, imported Anka machine tool with high precision grinding, fine polishing treatment. Sharp edge, smooth chip removal, durable wear.
2.Product specifications: blade diameter 0.30-3.175MM (0.1MM per gauge interval) shank diameter 3.175MM. total length 38MM (handle diameter and total tool length are fixed for all lengths)

3.Product material: imported ultra-fine grain tungsten carbide hard alloy

4.Product material: the blade is imported hard alloy (tungsten steel)

5.Features:
1. The space of the drill chip is large: the chip resistance is small, the chip discharge is smooth, the heat generated by the hole is small, and the drilling is reduced;
2. Extraordinary cutting edge sharpness: Due to the use of nanotechnology and advanced grinding technology, the cutting edge of the drill bit is sharper than before, which can reduce the cutting force, reduce the drilling rate and improve the quality of the hole wall;
3. Tool design based on customer application: The drill bit is rich in variety and can meet different application requirements. All parameters of the milling cutter, such as core thickness and core taper, have been carefully designed and effective.

Raw materials use the whole Taiwan bar / TG / general PCB board milling / environmental protection board and other high hardness sheet carbon fiber / fiberglass / synthetic stone / printed circuit board / CCL / PCB / PVC / acrylic / MDF / bakelite / super Hardwood/bamboo ordinary FR-4/CEM-3 board and environmental protection board/plastic and other precision parts processing have high processing efficiency/good control of board edge finish/high dimensional accuracy, good chip removal performance/chip sharpness/long service life.
