DIN 1869 Drill

The most common type of bit is a twist drill. The drill bit’s handle is fastened by the machine tool to provide rotational motion. Straight or tapered handles are available. The body of the bit is typically composed of two spiral grooves known as grooves. These grooves are characterized by a spiral Angle, which is normally about 30 degrees but can vary depending on the workpiece’s material qualities. The tip of the bit normally has an Angle of 118 degrees, a rear Angle of 10 degrees, and a cross edge. The chisel edge is flat, and the web thickness is around 0.015 x bit diameter. The edge can pose complications with hole placement because it might “wander” on the surface before engaging the workpiece. A drill Angle of less than 118° is utilized for brittle materials, whereas a bigger drill Angle and a smaller back Angle are used for ductile materials.

A DIY and industrial market favorite. 118 degree point, general purpose, appropriate for portable and machine drilling. Designed for low and medium carbon steel, cast iron, and wood processing. The 135-degree split point centralizes and decreases thrust automatically. For portable or machine drilling, low tensile strength alloy alloys, stainless steel, and other medium applications are appropriate. Brighten the finish using black oxide, titanium nitride coating, and bronze oxide. Customers will have more options.
