Spiraalborenset Bosch HSS PointTeQ 2608577350

Twist Drill Bit Set Bosch HSS PointTeQ 2608577350 contains 18 HSS twist drill bits engineered for fast, precise drilling in steel and cast iron. Each bit features the PointTeQ tip design and a cylindrical shank equal to the drill diameter, compatible with drill stands and handheld drill drivers. The bits are manufactured to DIN 338 as Type N with a 135° point and a black-oxide coated flute for improved chip evacuation.

Advantages

The PointTeQ tip design enables fast penetration and reduces walking at the start of drilling. High-speed steel construction provides durability and wear resistance for metalworking. A highly elastic body lowers the risk of breakage, particularly for diameters under 6 mm. The black-oxide coated flute promotes efficient chip removal and helps maintain cutting performance over repeated use.

Suitable for

• Drilling holes in steel
• Drilling in cast iron
• Use in drill stands and handheld drills
• General metalworking and maintenance tasks

How to use

Secure the appropriate drill bit in the chuck so the cylindrical shank seats firmly. Select the correct drilling speed for the bit diameter and workpiece material; use lower speeds for larger diameters and harder metals. Start drilling with light pressure to let the PointTeQ tip locate the position, then apply steady pressure. Periodically withdraw the bit to clear chips and prevent overheating. Use cutting fluid when drilling thicker or harder metals to extend bit life and improve hole quality.

Recommendations

For best results, match drill speed to material and bit size, use cutting lubricant on hard or thick sections, and avoid excessive side load to reduce the risk of breakage—especially for bits smaller than 6 mm.
