Drill bits Bosch HSS Twist PointTeQ — set for metal and wood, high-speed steel

Bosch HSS Twist PointTeQ drill bits are high-speed steel twist drills engineered for reliable drilling in metal and wood. The PointTeQ tip provides fast self-centering starts and reduced walking, enabling clean pilot and clearance holes with fewer corrections. Constructed from HSS with a black-oxide coated flute, these bits offer good wear resistance at higher cutting speeds and efficient chip evacuation. The cylindrical shank matches the drill diameter for secure clamping in hand drills and drill stands, and the Type N flute geometry with a 135° tip angle is suitable for drilling a range of materials while lowering the risk of breakage on smaller diameters.

Advantages

The PointTeQ geometry ensures quick centering and stable drilling starts, reducing the need for pilot marking. HSS construction provides durability under higher rotational speeds and repeated use. Black-oxide coated flutes improve chip flow and reduce friction, helping to control heat buildup. The straight cylindrical shank allows simple mounting in standard chucks and drill presses. The 135° split-point tip helps to penetrate hard surfaces with less walking and produces cleaner hole entry.

Suitable for

• Drilling clearance and pilot holes in alloyed and non-alloyed steel
• Drilling non‑ferrous metals such as aluminium and brass
• Drilling timber and wood-based materials
• Use with handheld drills and stationary drill presses

Key specifications

• Material: High-speed steel (HSS)
• Tip geometry: PointTeQ self-centering tip, 135° angle
• Flute coating: Black oxide for improved chip evacuation
• Flute type: Type N (standard spiral flute)
• Shank: Cylindrical shank matching drill diameter
• Standard: Manufactured to DIN 338

How to use

Select a drill bit size appropriate for the desired hole and material. Secure the workpiece and clamp if necessary to prevent movement. Fit the cylindrical shank securely in the drill chuck or press arbor. For metal, use moderate feed pressure and appropriate cutting speeds for HSS; for wood, higher spindle speeds can be used. Start drilling with steady axial pressure to allow the PointTeQ tip to self-center, and periodically withdraw the bit to clear chips. Apply cutting fluid or lubricant when drilling steel to extend tool life and reduce heat, and use air or brush to clear chips when drilling wood.

Usage recommendations

Use cutting lubricant for metal drilling, adjust speed and feed according to material hardness, and secure the workpiece to improve precision and extend the life of the HSS Twist PointTeQ bits.
