Drill bit Glob HSS trepanning 13 x 30 mm, length 30 mm, model GLOB-WT13S

Drill bit Glob HSS trepanning model GLOB-WT13S is a trepanning cutter with a cutting diameter of 13 mm and an overall length of 30 mm. Manufactured from high-speed steel (HSS), this trepanning drill bit is designed to produce precise circular holes in metal and other hard materials. It is compatible with hand-held drills and drill presses, offering a compact solution for tasks that require clean, round holes with minimal material waste.

Advantages

The HSS construction provides high hardness and heat resistance for sustained cutting performance when drilling ferrous and non-ferrous metals. The trepanning design removes a narrow ring of material rather than the full core, reducing cutting forces and allowing faster drilling of larger diameter holes with less power. The short overall length and precise cutting diameter help maintain hole concentricity and reduce vibration during operation.

Suitable for

• Creating precise circular holes in steel, aluminum, brass and other metals
• Maintenance and repair tasks requiring neat hole edges
• Fabrication and installation where minimal material removal is desired
• Use with hand-held drills and bench drill presses

Key specifications

• Cutting diameter: 13 mm
• Overall length: 30 mm
• Material: High-speed steel (HSS)
• Tool type: Trepanning drill bit (annular cutter)
• Intended materials: Metals and other hard materials

How to use

Secure the suitable drill or press chuck and ensure the workpiece is clamped firmly to prevent movement. Fit the trepanning drill bit into the chuck and set an appropriate spindle speed for the material being machined. Apply steady feed pressure and cooling or cutting fluid as required to reduce heat buildup and prolong tool life. Withdraw the cutter periodically to clear chips and check hole quality until the desired hole depth is reached.

Usage recommendations

Use cutting fluid when drilling ferrous materials to improve surface finish and extend tool life; select moderate spindle speeds for HSS trepanning to balance cutting efficiency and heat generation. Ensure proper clamping and alignment to maintain concentricity and reduce vibration.
