Drill Bit set Forsage 5.6 mm HSS+Co for metal, 10 pieces

Forsage 5.6 mm HSS+Co metal drill bit set, 10 pieces, is a collection of precision twist drills designed for drilling in a variety of metal materials. Each bit is ground from high-speed steel alloyed with cobalt to increase hardness and heat resistance, delivering extended tool life during repeated drilling operations. The set provides a consistent 5.6 mm diameter across all pieces, suitable for workshop and industrial applications where reliable, repeatable hole sizes are needed.

Advantages

The HSS+Co construction improves wear resistance and maintains cutting performance at elevated temperatures compared with standard HSS. Accurate flute geometry and point sharpening produce efficient chip evacuation and stable drilling behavior in steels and other metals. A set of ten identical bits ensures quick replacement on the job and reduces downtime when multiple holes of the same diameter are required. The solid, uniform manufacturing supports compatibility with common drill chucks and standard drilling machines.

Suitable for

• Drilling holes in mild and stainless steels
• General metalworking and maintenance tasks
• Workshop and light industrial production where repeated 5.6 mm holes are needed
• Repair and fabrication projects involving metal panels and plates

Key specifications

• Nominal diameter: 5.6 mm
• Material: high-speed steel with cobalt (HSS+Co)
• Type: twist drill bit
• Quantity in set: 10 pieces
• Suitable materials: ferrous metals, stainless steel, and similar alloys
• Shank style: straight round shank for standard chucks

How to use

Select an appropriate drill speed and use cutting fluid when drilling harder metals or stainless steel to reduce friction and heat. Secure the workpiece firmly in a vise or clamp to prevent movement. Mount the 5.6 mm bit in a compatible keyed or keyless chuck, ensure it is centered and tightened, then start drilling with moderate feed pressure. Periodically withdraw the bit to clear chips and, if necessary, reapply coolant to preserve tool life and hole quality.

Usage recommendations

For best results, pre-drill pilot holes when working with thick materials, use progressive peck drilling for deep holes, and match drill speed to the material hardness. Store the bits in a protective case to prevent edge damage between uses.
