Bosch HSS-Co CYL Spiral Drill Bit 10mm

The Bosch HSS-Co CYL Spiral Drill Bit 10mm is a precision-engineered tool designed for demanding drilling tasks in professional workshops and industrial settings. Manufactured from cobalt-alloyed high-speed steel, this 10mm spiral drill bit delivers exceptional heat resistance and structural durability, making it an essential accessory for heavy-duty metalworking applications.

Advantages

The cobalt-alloyed composition significantly increases the drill bit's resistance to high temperatures generated during continuous drilling operations. This material upgrade ensures that the cutting edge retains its sharpness longer than standard high-speed steel bits, resulting in extended tool life and reduced operational downtime. The precise manufacturing process guarantees accurate hole diameters and smooth finishing, which is critical when working with tough and abrasive materials. Furthermore, the robust construction minimizes the risk of breakage under high torsional loads.

Suitable for

• Drilling in stainless steel and alloyed steel
• Working with unalloyed steel and cast iron
• Processing hard plastics and synthetic materials
• Professional metalworking and workshop applications

When it may not be suitable

This drill bit is not optimized for drilling in soft materials such as wood, drywall, or soft non-ferrous metals where specialized geometry is required. It is also not recommended for use in standard rotary hammers without a proper cylindrical drill chuck adapter.

Key specifications

• Diameter: 10mm
• Material: Cobalt-alloyed high-speed steel (HSS-Co)
• Shank type: Cylindrical
• Application: Hard metals, stainless steel, cast iron, and plastics

How to use

Secure the drill bit firmly into a compatible drill chuck to ensure concentric rotation and prevent slipping during operation. Center the drill point accurately on the workpiece and apply steady, moderate pressure while maintaining an appropriate rotational speed suitable for the specific material being processed. Use cutting fluid or lubricant when drilling in hard metals to reduce friction, dissipate heat, and further prolong the lifespan of the bit. Clear the chips periodically from the hole to prevent clogging and overheating.

What to consider before purchase

• Verify that your drilling equipment is compatible with a 10mm cylindrical shank drill bit.
• Assess the hardness and type of materials you intend to process regularly.
• Ensure you have appropriate cooling lubricants available for metalworking applications.

Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses and gloves, when operating drilling tools. Maintain recommended drilling speeds to prevent premature tool wear and ensure operator safety.
