Name: Counterbore Drill Package: plastic box Material: cutter head YG8 alloy, cutter body 45# carbon steel, surface spraying
Packing size: 18mm*18mm*95mm Weight: 31 grams for a single piece, 155 grams for a 5-piece set, 11 grams for a 5-piece drill core set
Usage: Used for wood, aluminum alloy screw counterbore, opening Advantages: It has strong high temperature and wear resistance, and will not produce deformation and wear in high-temperature cutting, of course, there will be loss with the consumption of time, but the things that are made in the time without loss are precious,
and secondly, the toughness of the high-speed steel drill bit is far more than other materials, the drilling processing bit must not only maintain stability, the toughness requirements are also very high, without good toughness, the drill bit is prone to collapse, resulting in the instability of the hole diameter drilled out by the drill bit wear.
