Format Twist Drill Bit HSS-Co Cylindrical Shank 10.2 mm

The Format Twist Drill Bit HSS-Co Cylindrical Shank 10.2 mm is a high-performance cutting tool engineered for demanding drilling tasks in professional environments. Manufactured from high-speed steel alloyed with cobalt, this drill bit offers superior thermal resistance and extended tool life when operating at high speeds. The precision-ground cylindrical shank ensures a secure and stable fit in standard drill chucks, enabling accurate hole placement and reliable performance across various metalworking applications.

Advantages

The incorporation of cobalt into the high-speed steel composition significantly increases hardness retention under high operating temperatures, reducing wear during continuous drilling operations. The robust construction provides excellent torsional rigidity, minimizing the risk of breakage when encountering hard materials. Its optimized flute geometry ensures efficient chip evacuation, which prevents overheating and contributes to clean, burr-reduced hole creation.

Suitable for

• Drilling alloyed and unalloyed steels
• Machining stainless steel and cast iron
• Professional workshop maintenance and metal fabrication
• General manufacturing and industrial repair tasks

When it may not be suitable

This drill bit is not recommended for drilling non-metallic materials such as wood, plastic, or masonry, as the cutting geometry and material composition are specifically optimized for metals. It may also be less efficient when used in low-power handheld drills without proper speed control.

Key specifications

• Diameter: 10.2 mm
• Shank type: Cylindrical
• Material: High-speed steel with cobalt content (HSS-Co)
• Application: Metalworking and stainless steel drilling

How to use

Secure the cylindrical shank firmly into the drill chuck to prevent slipping during operation. Mark the drilling spot with a center punch to ensure accurate positioning and prevent the bit from wandering. Apply consistent and moderate axial pressure while maintaining an appropriate rotational speed compatible with the workpiece material. Utilize cutting fluid or lubricant to dissipate heat, reduce friction, and extend the operational lifespan of the tool.

What to consider before purchase

• Verify that your drill chuck is compatible with a 10.2 mm cylindrical shank diameter.
• Ensure your equipment is capable of providing the correct RPM and torque required for drilling alloyed and stainless steels.
• Assess whether the material hardness matches the operational capabilities of HSS-Co cutting tools.

Usage recommendations

Always wear appropriate personal protective equipment, including safety glasses and protective gloves, during drilling operations. Regularly inspect the cutting edges for wear and maintain proper lubrication to ensure optimal performance and safety.
