Drill bit for metal Forsage 6.35 mm HSS+Co set of 10

Set of 10 Forsage metal drill bits with a diameter of 6.35 mm, manufactured from HSS+Co (high-speed steel with cobalt). These bits are designed for drilling steel and a variety of other metals and alloys. The cobalt-enriched composition increases heat resistance and wear life compared with standard HSS, making the set suitable for repeated use in demanding metalworking applications. The shank size and straight-flute design make the bits compatible with standard hand drills and drill presses for general workshop and field work.

Advantages

The HSS+Co material provides improved hardness at elevated temperatures and better edge retention, which reduces the frequency of resharpening. A consistent 6.35 mm diameter ensures repeatable hole sizes for assembly and fabrication tasks. Supplied as a set of ten, the range offers quick replacements during production or maintenance operations, reducing downtime. The straight shank fits common chucks without adapters, supporting use in both portable and stationary drilling equipment.

Suitable for

• Drilling mild and hardened steels
• Metal fabrication and repair work
• Maintenance tasks in workshops and service vehicles
• Use with hand drills and drill presses

Key specifications

• Material: high-speed steel with cobalt alloy (HSS+Co)
• Diameter: 6.35 mm
• Quantity: set of 10 drill bits
• Tip style: standard twist point suitable for metal
• Shank type: straight shank for standard chucks

How to use

Secure the workpiece and mark the drilling position before starting. Use a suitable cutting lubricant when drilling metals to reduce heat buildup and prolong tool life. Clamp the bit firmly in the drill chuck, align perpendicular to the surface, and start at low speed to establish the hole, then increase speed as appropriate for the material. Apply steady, moderate pressure and allow the bit to clear chips regularly to prevent clogging and overheating. After use, clean chips from flutes and store the bits in a dry place.

Usage recommendations

For best results when drilling steel and harder alloys, use a cutting fluid and maintain moderate spindle speed. When encountering large-diameter or deep holes, withdraw the bit periodically to remove chips and prevent overheating. Replace worn bits to maintain hole accuracy and reduce risk of workpiece damage.
