## Long description

The Format Spiral Drill Bit HSS-Co Cylindrical 11.5 mm is a precision high-speed steel twist drill bit engineered for demanding professional applications. Featuring an 11.5 mm diameter and a cobalt-alloyed HSS-Co construction, this cutting tool offers enhanced heat resistance and extended durability when working with tough metals. It is specifically designed to provide reliable performance in both alloyed and unalloyed steel, cast steel, and stainless steel.
Advantages
The incorporation of cobalt into the high-speed steel composition significantly improves thermal resistance, allowing the drill bit to maintain its cutting edge even under high friction and elevated temperatures. Its precision grinding ensures accurate hole dimensions and clean finishes, reducing the need for secondary deburring or processing. The robust construction minimizes the risk of breakage during high-load operations, delivering consistent results and high productivity in professional workshop and industrial environments.
Suitable for
Drilling alloyed and unalloyed steels
Machining stainless steel and cast steel
Professional metalworking and fabrication tasks
Workshop maintenance and repair operations
When it may not be suitable
This drill bit is not recommended for drilling soft non-ferrous materials like wood, plastic, or aluminum, where high cobalt content and specialized geometry are unnecessary. It is also unsuitable for hand-held drilling tasks requiring flexibility or tools without standard cylindrical chuck compatibility.
Key specifications
Diameter: 11.5 mm
Material: High-Speed Steel with Cobalt alloy (HSS-Co)
Shank type: Cylindrical
Application range: Alloyed steel, unalloyed steel, cast steel, stainless steel
How to use
Secure the cylindrical shank firmly into a compatible drill chuck or drill press to ensure stability and prevent slippage during operation. Align the drill bit perpendicularly to the workpiece surface and apply steady, controlled pressure. Use an appropriate cutting fluid or lubricant to dissipate heat effectively, prolong the lifespan of the cutting edge, and ensure optimal chip evacuation, particularly when working with stainless steel and hard alloyed metals.
What to consider before purchase
Verify that your drill or drill press chuck is compatible with an 11.5 mm cylindrical shank
Ensure your equipment is capable of delivering the appropriate torque and speed for drilling hard metals
Confirm the material requirements of your project match the steel and stainless steel capabilities of this cobalt drill bit
Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses and gloves, when performing metal drilling operations. Regularly inspect the cutting edges for wear and apply a suitable cooling lubricant during extended drilling sessions to maximize tool longevity.
