Product description
Material: High speed steel
Widely applicable: Widely used in drilling and positioning of plastics, ceramics, and wood, suitable for various fields
High quality carbon steel, with high overall heat treatment hardness, high torque, and good toughness
The design of the steel wire hole can lock the drill bit loudly without causing drilling deviation
The drill bit shown in the picture does not include a price limit, and the drill bit must be purchased separately!
The main function of the limit ring is to fix it on the drill bit, limit the depth of the borehole, and make the depth of the borehole consistent, which is more comfortable for using round tenons.
