Product Information

Full details

The Bosch HSS Twist Drill Bit PointTeQ is designed for professionals and DIY enthusiasts who need fast, accurate drilling in a variety of metals and plastics. Its key benefit is the self-centering PointTeQ tip, which ensures quick, precise starts without wandering, and an increased drilling rate that reduces heat and wear for extended durability. A minor consideration is that optimal performance is achieved with appropriate drill stands or drivers, as specified for its cylindrical shank system.

FAQs

What types of metal can the PointTeQ HSS drill bit be used on?

This bit is suitable for drilling alloyed and non-alloyed steel, non-ferrous metals, cast steel, and cast iron.

What is the main advantage of the PointTeQ tip?

The PointTeQ tip is self-centering, which allows for fast and precise drilling starts without the bit wandering across the surface.

Is this bit suitable for plastics?

Yes, the Bosch HSS Twist Drill Bit PointTeQ is also suitable for drilling plastics.

How does the design reduce breakage?

The bit features a highly elastic body, especially in diameters below 6 mm, which makes it more resilient and less prone to snapping during use.

What does DIN 338 compliance mean?

It means the drill bit is manufactured according to the German Institute for Standardization (DIN) standard 338, ensuring specific quality and dimensional requirements for twist drill bits.

Can I use this bit with a standard cordless drill?

Yes, it is intended for use with drill drivers and drill stands. Ensure the bit is securely clamped in the chuck.

How should I clean the drill bit after use?

After use, clean the bit with a brush to remove metal shavings and debris. Store it in a dry place to prevent rust.

Troubleshooting

Drill bit wanders on the surface before starting.

Ensure the PointTeQ tip is properly engaged with the material. For very hard materials, consider using a center punch to create a small indentation for the bit to start in.

Bit is not drilling effectively or quickly.

Check if the drill speed is appropriate for the material. Ensure the flute is clear of chips. Re-sharpening or replacing the bit may be necessary if it has become dull.

Excessive heat generation during drilling.

Reduce drilling pressure or speed. Ensure chips are being cleared effectively by the flute. Use a cutting fluid if drilling continuously in tough metals.

Drill bit breaks during use.

Reduce excessive side-load or bending force on the bit. Ensure the correct drilling speed and feed rate are used. For bits under 6mm, the elastic body helps, but care is still needed.

Pros and Cons

Pros

  • Fast and precise drilling starts due to the PointTeQ tip.
  • Reduced heat and wear lead to a longer tool life.
  • Durable tip design ensures consistent performance.
  • Lower risk of breakage, especially for smaller diameter bits.
  • Efficient chip removal for cleaner cuts.
  • Suitable for a wide range of common metals and plastics.

Cons

  • Requires appropriate drill stands or drill drivers for optimal use.
  • Specific to drilling clearance and pilot holes, not designed for countersinking or complex hole shaping.
  • The 3.9mm diameter bit may be too small for some heavy-duty applications.

Setup, Compatibility & Care

Setup:

  1. Select the Correct Bit: Choose the appropriate PointTeQ HSS drill bit size for your intended hole diameter.
  2. Insert into Chuck: Securely insert the bit's cylindrical shank into the chuck of your drill stand or drill driver.
  3. Set Speed: Use an appropriate speed setting for metal drilling, typically a medium to high speed depending on the material and bit size.

Compatibility:

  • Drill Type: Intended for use with drill stands and drill drivers.
  • Materials: Suitable for alloyed and non-alloyed steel, non-ferrous metals, cast steel, cast iron, and plastics.
  • Standards: Manufactured to DIN 338 (Type N, 135-degree tip).

Care:

  • Cleaning: After use, clean the bit to remove metal shavings and debris. A brush can be effective.
  • Storage: Store bits in a dry environment to prevent corrosion. The original packaging or a dedicated drill bit organizer is recommended.
  • Lubrication: For prolonged drilling in metal, consider using a cutting fluid to further reduce heat and improve performance, though the bit's design inherently manages heat well.
