Â

The height of the drill bit for shorts body is generally 50-55mm; The height of Long skirt drill bit is generally above 60mm.

Taper Angle (Degree): 4Â°46â€²,7Â°,11Â°,12Â°

Dia.: 28mm,30mm, 32mm, 34mm, 36mm, 38mm, 40mm, 42mm, 46mm, 48mm, 50mm, 55mm, 60mm70mm, 80mm

Drillers choose tapered button bits for faster drilling penetration rate. Different taper sizes have different characteristics when it comes to the "knock-off" index - the smaller angle will prevent the bit from spinning.

Â
