solid drill bit / HSS / helical

RUKO presents a multi-purpose twist drill for usage in boring devices as well as wireless bores. It features a 3-base shank for exceptional attachment within the bore chuck with effortless operation. Additionally, the 135? greater performance cutting tip guarantees a superior accuracy especially when operated manually using a wireless boring device.

The border resists the gliding of the grooved surfaces during spot-boring. Owing to the fewer cutting pressures, the damage resistance of the rechargeable battery is highly enhanced. The black bevel can rise the damage resistance and offer protection against cold fusing and build-up borders. Moreover, the 40? helix angle allows for a precise and instant block elimination along with a greater cutting pace, solidity and precision.
