Product information

Description

The Format Spiral Drill Bit HSS-Co Straight Shank 4.2mm is a high-performance cutting tool engineered for demanding drilling tasks in professional workshops and industrial environments. Manufactured from a premium high-speed steel alloy containing cobalt (HSS-Co), this drill bit offers exceptional hardness, wear resistance, and superior heat tolerance during continuous operation. Its precision-ground geometry ensures accurate centering and clean chip evacuation when working with tough metallic workpieces.

Advantages

The inclusion of cobalt in the alloy composition significantly enhances the tool life of the Format spiral drill bit, allowing it to maintain cutting edge sharpness even under elevated temperatures generated during high-speed drilling. The straight cylindrical shank provides secure chuck gripping and reliable torque transmission across various standard drilling equipment. This robust construction minimizes deflection and breakage risks, delivering consistent precision and repeatability for high-volume production and maintenance tasks.

Suitable for

  • Drilling stainless steel and acid-resistant metals
  • Machining alloyed and unalloyed steels
  • Working with cast iron and bronze
  • Professional workshop repairs and metal fabrication

When it may not be suitable

This drill bit is not optimized for drilling soft materials such as wood, plastics, or standard masonry, as the specialized geometry and cobalt alloy are specifically balanced for metal-cutting efficiency. Using it on non-recommended materials may lead to clogging or suboptimal hole quality.

Key specifications

  • Diameter: 4.2 mm
  • Material: HSS-Co (Cobalt alloyed high-speed steel)
  • Shank type: Straight cylindrical shank
  • Application type: Metal and hard material drilling

How to use

Insert the straight shank securely into the drill chuck and tighten evenly to prevent slippage during operation. Ensure the workpiece is firmly clamped to avoid movement and potential bit breakage. Apply appropriate cutting fluid or lubricant to extend tool life and improve surface finish when drilling hard metals. Maintain a steady feed rate and moderate rotational speed corresponding to the material hardness to achieve optimal performance.

What to consider before purchase

  • Verify that the 4.2 mm diameter matches your specific hole size requirements
  • Confirm that your drill chuck is compatible with straight cylindrical shanks
  • Ensure you have appropriate cooling lubricants available for cutting hard metals
Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses and gloves, during metal drilling operations. Regularly inspect the cutting edges for wear and replace the drill bit when dull to maintain precision and prevent excessive heat buildup.
