High Speed Steel Multi-Fork Drill Bit (M-25)

Advantage:

1)Unique grinding technique to reduce 85%~90% of length of chisel edge, and the axial resistance of drilling decreased about 50%. The pyramid drilltip has excellent centering performance.
2)135° Point angle of outer edge with arc blade brings good sub-chip performance, 17% drilling torque reducing, more faster drilling speed, and larger drilling hole by small machine.
3)After centering, like drawing the circle by compasses, JAtech multi-fork twist drill bit will make the borehole rounder, more smooth, and burrs less. It's suitable for variety of thin plate materials, such as carton steel, aluminum, stainless steel, and brass, after choosing the drilling parameters. Especially for electric hand drill, JAtech multi-fork twist drill bit has its unique advantages as below:
A. JAtech multi-fork twist drill bit is good at 0.2mm~3.0 thin plate, multiple thin plates, flat surface and arc surface.
B. Because of excellent performance of sub-chip and chip removal, JAtech multi-fork twist drill is able to drill the thick plate which its thickness is 3 times of bit Dia.
C. In the motor feed drilling machine, hole depth is less than 5 times of bit diameter, it advanced with the rest of the world performance similar to the twist drill.
