Trepan drill bit Glob HSS 13 x 50 mm, length 50 mm, model GLOB-WT13L

Trepan drill bit Glob HSS 13 x 50 mm, model GLOB-WT13L, is a hole saw designed for cutting and enlarging circular holes in metal and other materials suitable for high-speed steel (HSS) tools. The tool has a working length of 50 mm and a 13 mm cutting diameter, making it appropriate for precision through-holes and fitting operations in workshop and industrial environments. It is intended for use with compatible drill chucks or arbors and is manufactured from high-speed steel to provide hardness and wear resistance for typical machining tasks.

Advantages

The HSS material ensures consistent cutting performance and resistance to heat buildup during moderate-speed drilling. Its 13 mm diameter and 50 mm working length offer a balance between reach and rigidity, enabling accurate hole cutting and enlargements. The trepan design removes a core rather than grinding the full material, reducing cutting forces and improving chip evacuation compared with solid drills for similar hole sizes.

Suitable for

• Creating and enlarging circular through-holes in sheet metal and light structural components
• Workshop fitting and assembly tasks requiring precise diameter holes
• Preparation of holes for fasteners, bushings, or pipes in compatible materials

Key specifications

• Cutting diameter: 13 mm
• Working length: 50 mm
• Material: High-speed steel (HSS)
• Tool type: Trepan / hole saw drill bit
• Compatibility: Designed for use with drill chucks or arbors that accept HSS trepan bits

How to use

Secure the trepan bit in a compatible drill chuck or arbor and verify the bit is tightened correctly. Mark the drilling position on the workpiece and clamp the workpiece to prevent movement. Start drilling at low speed to establish the cut, then increase speed within recommended limits for HSS tools while applying steady, moderate feed pressure. Periodically withdraw the bit to clear chips and reduce heat; use cutting fluid as appropriate for the material to improve tool life and hole quality. After reaching the desired depth or completing the through-hole, stop the drill and remove any remaining core carefully.

Usage recommendations

Use appropriate cutting speeds and cooling for the specific material being drilled. For thicker or harder materials, use cutting fluid and controlled feed to reduce wear. Inspect the bit before use for signs of wear or damage and replace it when cutting performance deteriorates to maintain hole accuracy and safety.
