Högert Step Drill Spiral Form D 4 - 32 mm

Step Drill Bit Spiral Shape Ø 4 - 32 mm

Spiral step drill bit, suitable for drilling in various steel grades, non-ferrous metals, plastics, and wood. It allows drilling precise holes. The drill bit has a spiral cutting groove, which is one of the most effective technologies used in step drill bits, enabling much faster and more efficient drilling, while maintaining precise stepped edges. It can be used in roofing workshops, car repair workshops, or by installers and electricians. For professional use.

• made of hardened HSS 4241 high-speed steel;
• a special titanium nitride coating increases durability and quadruples the service life;
• precision, with high drilling speed;
• the uncoiled and thicker core provides crack resistance during use;
• diameter of 4 – 32 mm;
• number of steps: 15 (4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32 mm);
• efficient chip and heat removal reduces the risk of overheating and increases the drill bit's lifespan;
• two spiral cutting grooves significantly increase working speed, efficiency, and the drill bit's lifespan;
• 1/4 HEX drive for quick and secure assembly on drilling machines, screwdrivers, and adapters;
• 118 degree point angle and conical shape of the drill bit - pre-drilling or scoring is not required;
• Auto-Deburring - automatic deburring and smoothing of edges while drilling, eliminating the need for manual post-processing of the drilled hole;
• manufactured according to DIN 1412C;
• the maximum material thickness is 4 mm;
• markings on the surface of the drill bit allow you to monitor the correct size of the drilled hole.
