Glob HSS Trepan Drill Bit 30 mm cutting depth 19 mm diameter

The Glob HSS Trepan Drill Bit with a cutting depth of 30 mm and a diameter of 19 mm is a high-speed steel core drill designed for precise and efficient metal drilling applications. This tool delivers clean holes and reliable performance, making it a suitable choice for professional workshop and industrial environments where accuracy and durability are essential.

Advantages

Manufactured from high-speed steel, this trepan drill bit offers excellent wear resistance and structural integrity during intensive metal-working operations. Its core drilling design reduces the amount of material that needs to be cut, resulting in faster drilling speeds and lower energy consumption compared to traditional solid twist drills. The precise geometry ensures clean hole walls and accurate diameter dimensions, which streamlines subsequent assembly and fitting processes in professional manufacturing and repair tasks.

Suitable for

• Drilling holes in structural steel and metal plates
• Professional workshop and industrial manufacturing operations
• Metal fabrication and engineering projects
• Creating clean core holes with minimal material waste

When it may not be suitable

This drill bit is not designed for drilling non-metallic materials such as wood, plastics, or masonry, as the high-speed steel geometry and core-cutting design are optimized specifically for metal applications. Additionally, it is not recommended for handheld drilling operations without adequate stabilization, as core drills require proper alignment and rigid setup to prevent tool breakage.

Key specifications

• Material: High-speed steel (HSS)
• Cutting depth: 30 mm
• Diameter: 19 mm
• Tool type: Trepan core drill bit

How to use

Secure the workpiece firmly to prevent any movement during the drilling process. Mount the trepan drill bit securely into a compatible magnetic core drilling machine or stationary drill press designed for annular cutters. Align the center pin of the tool with the pre-marked center point of the hole. Apply a consistent and appropriate feed rate while using a continuous supply of cutting fluid or lubricant to dissipate heat and extend the service life of the cutting edges. Clear away any metal chips from the hole area upon completion.

What to consider before purchase

• Verify that your drilling equipment is compatible with 19 mm core drills and can accommodate the 30 mm cutting depth.
• Ensure you have a reliable supply of metal cutting fluid or lubricant for operation.
• Check that the workpiece material matches the intended metal-drilling capabilities of high-speed steel core drills.

Usage recommendations

Always wear appropriate personal protective equipment, including safety glasses and gloves, during metal drilling operations. Ensure the machine speed and feed rate are properly adjusted according to the material specifications to maintain optimal cutting performance and prevent premature wear.
