Drill bushings, also known as positioning bushings, are essential components in metalworking and mechanical engineering. They provide precise guidance for drills and other tools to ensure accurate drilling in various materials.
At Winco, you will find drill bushings and
positioning bushings according to DIN 179 and DIN 172 in various lengths and shapes. Both collar drill bushings and cylindrical drill bushings are available in the online shop.
Positioning Bushings DIN 172 – Collar Drill Bushings
Collar drill bushings from Winco are made from special tool steel, hardened, and ground according to DIN 172. Their distinctive feature is the protruding collar, which prevents the bushing from being pressed through the holder during use.
Positioning Bushings DIN 179 – Cylindrical Drill Bushings
Drill bushings according to DIN 179 are cylindrical bushings. They are made from special tool steel and are also hardened and ground. Due to their cylindrical shape, the bushing can be pressed flush into the holder.
Positioning Bushings with Tapered Bore
Positioning bushings DIN 172.1 with a collar or positioning bushings DIN 179.1 without a collar serve as detent holes for the detent pins GN 817.5.
