Silverline Tools Cobalt Split Point Drill Bit 19 Piece Set in Storage Organiser Case

MPN: 196503 

Barcode: 5055058112200

Overview:

Cobalt Split Point Drill Bit 19 Piece Set in Storage Organiser Case (196503) is built for confident drilling in tougher materials where standard bits struggle. Manufactured to DIN338 from M35 high speed steel with 5% cobalt, these fully ground bits offer improved strength, heat resistance and wear performance for regular metalworking and engineering tasks. Each bit features a 135° split point that self-centres to reduce wandering, helping you start cleaner holes with less pressure. Supplied in a durable organiser case with marked size slots, the set covers 1mm to 10mm in 0.5mm increments for excellent day-to-day coverage.

Applications

• Drilling harder metals and tougher materials (bit selection dependent)

• Workshop fabrication, engineering and maintenance work

• Accurate pilot holes and repeat drilling where reduced wandering matters

• General metalworking tasks using a suitable drill and speed

• Jobs requiring a broad set of sizes without constant bit changes

How to Use

• Select the correct bit size and ensure it’s secured in the chuck

• Mark the hole position and clamp the workpiece securely

• Use a suitable cutting fluid/cooling agent for metal drilling

• Drill at the correct speed with steady, controlled pressure

• Clear swarf regularly and allow the bit to cool on repeated holes

• Store bits back in the case after use to keep edges protected

Cobalt Split Point Drill Bit Set – Key FAQs

• What is the advantage of cobalt drill bits?

  • Cobalt bits (M35 with 5% cobalt) offer improved heat resistance and wear performance, making them better suited to tougher materials and repeated drilling than basic HSS bits.

• What does a 135° split point do?

  • A 135° split point self-centres as it starts the hole, reducing “walking” on harder surfaces and helping you drill more accurately with less pressure.

• What sizes are included in this 19pc set?

  • The set covers 1.0mm to 10.0mm in 0.5mm increments, giving you 19 commonly used sizes for workshop and engineering tasks.

• Do I need to use cutting fluid?

  • Yes, using a cooling agent/cutting fluid is recommended to improve tool life, reduce heat build-up and help produce cleaner holes in metal.

• What does DIN338 mean?

  • DIN338 is a recognised manufacturing standard for drill bit geometry and dimensions, helping ensure consistent performance and compatibility for general-purpose twist drills.

• How is the set stored?

  • The bits come in a plastic organiser case with individual size slots, making it easy to find the right bit quickly and keep the set protected in storage.
