Carbide Drill Sleeve
Cemented carbide drilling die sleeve has a high hardness, wear resistance, strength and toughness, heat, corrosion and a series of excellent performance, especially its high hardness and wear resistance, even at 500 ℃ temperature also basically remain unchanged, in 1000 ℃ still have a high hardness.

At present, Dongguan Xia Yang Precision Tungsten Steel Co., Ltd. has been processed: straight-type bushing (into the son), the continuous-style bushing, special-shaped bushing, the pipe mold core, carbide drilling kits.
1. Straight-type bushing (into the son), the inside hole φ1.0 above, the electronic hardware factory continuous drawing die Inserts, the hardness is high, the inner wall is smooth, the stretch product surface is smooth, has no pull mark, the life expectancy is over 1 million.
2. Special-shaped bushing, oval square inside hole, electronic hardware factory continuous die Inserts, high hardness, good inner hole finish, tensile products, high surface quality, long life, suitable for large-scale production.
3. Connecting bushing, hardware electronics factory stretching and connecting bushing to solve the problem that the continuous mold step is too narrow
4. Drawing die concave die ∮180*∮95*40, hardware factory pull 1.5 thick cold rolled barrel, hardness high, smooth friction coefficient small, stretching product surface without scratches, service life up to 1.5 million times 5. Liner Tin Coating, hardware electronics factory for specific purposes, tin coating to make tungsten steel bushing smoother and more durable
