Product Information

Full details

The Starrett HSS Split Point Drill Bit (KDHSP020) is an essential tool for professional tradespeople and metalworkers who require high-precision drilling in demanding applications. Featuring specialized heat-treated body strength and a 2.0mm precision-ground tip, this bit provides consistent, reliable penetration in tough materials; however, users should note that as a 2.0mm bit, it requires careful handling and consistent speed to avoid snapping during high-torque operations.

Extended Product Information

FAQs

What is the diameter and length of this bit?

This specific model (KDHSP020) has a 2.0mm tip diameter, a 24mm working length, and a 49mm overall length.

Can this drill bit be used on stainless steel?

Yes, the HSS construction and heat treatment make it suitable for professional applications including various metals, provided you use the correct speed and lubrication.

Do I need to center-punch before drilling?

While the split point design helps prevent walking, a light center-punch mark is still recommended for extreme precision.

What does DIN 338 signify?

DIN 338 is a German standard that defines the dimensions and tolerances for jobber-length twist drills, ensuring they meet professional quality benchmarks.

Are there larger sizes available?

Yes, Starrett offers a range of sizes in this series, including 3.0mm, 4.0mm, 5.0mm, 6.0mm, 7.0mm, and 12.0mm versions.

Troubleshooting

Bit is wandering or skating on the metal surface

Ensure the drill speed is controlled and apply slightly more initial downward pressure to allow the split point to engage.

Bit is overheating and losing sharpness

Use a suitable cutting lubricant during the operation and ensure you are not applying too much pressure, which increases friction-based heat.

Excessive chip buildup in the hole

Periodically back the bit out of the hole while drilling to clear the debris, utilizing the flute geometry effectively.

Pros and Cons

Pros

  • High-strength material composition for long service life
  • Excellent centering precision due to the split point design
  • Efficient chip clearance prevents clogging in metalwork
  • Consistent performance across repeated drilling tasks

Cons

  • Small 2.0mm diameter makes it susceptible to snapping if side-loaded
  • Requires precise drill speed control for optimal results
  • Limited to smaller hole diameters due to specific size specifications

Setup, Compatibility & Care

To achieve the best results, ensure your drill chuck is properly tightened and the bit is seated centered. This bit is designed for use in standard handheld power drills and drill presses. Avoid applying excessive side pressure, as the 2.0mm thickness is fragile when subjected to lateral forces. After use, wipe the bit with a light machine oil to prevent surface oxidation, especially if the drill bit was used in damp conditions. Store the bit in a protective casing or bit organizer to prevent the precision tip from dulling against other metal tools.
