Description:

YG8 Tungsten Carbide
YG8 Tungsten Carbide also known as ISO K30 Tungsten Carbide.
Which density is about 14.5-14.9 g/cm3. The hardness of it is about HRC.70.The bending strength of it is 1500σbb/MPa and the the impact toughness is about 2.5J/cm2.
The tungsten carbide drill bit head is harder, tougher, and more resistant to extreme loads.

Different between Single-Flute Head and Double-Flutes Head:
Double-Flute Head ：Double-Flute Head style has rows of cutting teeth cut in two intersecting directions for fast material removal and a rougher finish, better than single flute design in cutting low hardness or medium hardness material.
Single-Flute Head:Double-cut style design to reduce bit stress,better than double flutes design in cutting high hardness material.(If you prefer to single-flute head style or other size, just take a look in our store)

Features：
USEGE - The carbide alloy rotary file main supporting the use of electric tool or the use of electric tool or the pneumatic tool (may also install on machine tool).
MULTIFUNCTION - Can be processed cast iron, cast steel, carbon steel, alloy steel, stainless steel, copper, aluminum and other metals, and marble, jade, bone and other non-metallic.Processing hardness up to HRA85.
HIGH QUALITY - Good processing quality, high finish. Can be processed into a variety of high-precision shape mold cavity.
LONG SERVICE LIFE - Long service life Durability than high-speed steel tool to improve 10 times, more than 200 times higher than the small grinding wheel.
Packed with nice plastic case for safety storage and protection.
