Drill bit set KREATOR KRT012701 — cobalt, 6 pieces

KREATOR KRT012701 — cobalt, 6 pieces is a compact set of six cobalt alloy drill bits engineered for drilling hard materials and a range of metals. The set delivers higher heat resistance and improved wear life compared with standard high-speed steel bits, making it suitable for repeated metal drilling operations. Each bit features a geometry adapted for metal removal and dimensional stability under higher temperatures.

Advantages

The cobalt composition increases red-hardness, allowing the bits to retain hardness at elevated temperatures and resist wear during prolonged use. Precision-ground flutes promote efficient chip evacuation to reduce clogging and heat buildup. The uniform shank diameter ensures secure clamping in standard drill chucks. The set format provides a range of commonly used diameters in a single compact package for workshop or site use.

Suitable for

• Drilling stainless steel and alloy steels
• Maintenance and repair work in workshops and industrial settings
• Fabrication tasks where higher heat resistance is required
• Drilling in cast iron and non-ferrous metals

Key specifications

• Material: cobalt alloy cutting edges
• Quantity: 6 drill bits per set
• Application: metalworking and hard-material drilling
• Flute type: spiral flutes for chip evacuation
• Shank: straight shank compatible with standard chucks

How to use

Select the correct drill diameter for the hole required and secure the drill bit in a suitable chuck. Use appropriate cutting speed and feed for the material being drilled, reducing speed for stainless and high-alloy steels. Apply cutting fluid or coolant when drilling metals to reduce heat and prolong tool life. Start drilling with a pilot hole if necessary, maintain steady pressure without forcing the bit, and retract periodically to clear chips.

Usage recommendations

Use safety equipment including eye protection and gloves. Match drilling speed and lubrication to the specific metal type, and inspect bits for wear before reuse to ensure consistent performance and safety.
