Product information

Description

The Format Twist Drill Bit HSS-Co Cylindrical 3.5 mm is a high-performance cutting tool engineered for precision drilling in demanding metallic materials. Manufactured from high-speed steel enriched with cobalt, this 3.5 mm twist drill offers superior heat resistance and extended durability compared to standard steel drill bits. Its robust construction ensures reliable performance during continuous operations in professional workshops and industrial environments.

Advantages

The inclusion of cobalt in the HSS-Co alloy significantly enhances the tool's hardness and thermal resistance, allowing it to maintain cutting efficiency even under high friction and elevated temperatures. The precision-ground cylindrical shank provides a secure and stable grip in standard drill chucks, minimizing slippage and ensuring accurate hole placement. This results in clean, precise cuts and reduces the risk of bit breakage during operation.

Suitable for

  • Drilling in alloyed and unalloyed steels
  • Machining cast steel and grey cast iron
  • Professional workshop applications
  • Industrial manufacturing tasks

When it may not be suitable

This drill bit is not optimized for drilling in softer materials such as wood or plastics, where high helix angles and different flute designs are typically required. It is also generally not recommended for heavy masonry or reinforced concrete drilling without appropriate hammer-action support, which requires specialized masonry bits.

Key specifications

  • Diameter: 3.5 mm
  • Material: High-speed steel with cobalt content (HSS-Co)
  • Shank type: Cylindrical
  • Application: Metal drilling

How to use

Ensure the workpiece is securely clamped and stable before beginning any drilling operation. Insert the cylindrical shank firmly into the drill chuck and tighten it evenly to prevent wobbling. Align the tip of the 3.5 mm drill bit perpendicularly to the surface of the material. Apply steady, moderate pressure while maintaining an appropriate rotational speed compatible with the metal being processed. Use cutting fluid or lubricant during extended drilling tasks to prolong the lifespan of the cutting edge and improve surface finish.

What to consider before purchase

  • Verify that the 3.5 mm diameter matches your specific hole size requirements
  • Confirm that your drilling equipment is compatible with cylindrical shank bits
  • Check that the target material falls within the recommended metal categories
Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses, when operating drilling tools. Periodically inspect the cutting edge for wear or damage to ensure consistent performance and safety.
