Twist Drill Bit Set Bosch HSS PointTeQ 5 pcs

Twist Drill Bit Set Bosch HSS PointTeQ 5 pcs contains five high-speed steel (HSS) twist drills engineered for drilling in steel and cast iron. The PointTeQ tip geometry and black-oxide fluted surface support rapid cutting and efficient chip evacuation. These cylindrical-shank drill bits conform to DIN 338 and have a 135° tip angle and Type N flute, making them suitable for use in drill presses and handheld drill drivers.

Advantages

The PointTeQ tip design reduces the risk of walking and allows fast penetration into metal. A highly elastic HSS body lowers the likelihood of breakage on smaller diameters. Black-oxide coating on the flutes improves chip removal and provides moderate surface protection, while the DIN 338 manufacturing standard ensures dimensional consistency and compatibility with standard chucks.

Suitable for

• Drilling holes in steel
• Drilling in cast iron
• Use in drill presses and handheld drill drivers
• General metalworking and maintenance tasks

How to use

Secure the required drill bit in the chuck so the cylindrical shank seats correctly. Select appropriate spindle speed for the drill diameter and the metal being worked—lower speeds for larger diameters and harder materials. Use cutting lubricant when drilling steel or cast iron to extend drill life and improve chip flow. Apply steady, moderate feed pressure and clear chips regularly to avoid clogging the flutes.

Usage recommendations

For best results, start with a center punch to prevent wandering, use correct speeds and lubrication for the material, and clamp workpieces securely. Replace bits that show excessive wear or damage to maintain drilling accuracy and safety.
