Glob HSS Core Drill Bit 18 x 30 mm

The Glob HSS Core Drill Bit 18 x 30 mm is a high-performance annular cutter engineered for precise and efficient metal drilling applications. Crafted from durable high-speed steel, this tool is designed to deliver clean holes, minimize cutting resistance, and provide an extended operating lifespan. It serves as a reliable solution for professional workshops, industrial manufacturing environments, and metal fabrication tasks where consistent accuracy and dependable performance are required.

Advantages

Manufactured from premium high-speed steel, the Glob HSS core drill bit offers exceptional durability and thermal resistance during intensive metal cutting operations. Its advanced geometry ensures smooth chip evacuation and reduced cutting resistance, which helps to minimize machine strain and operator fatigue. By cutting only the periphery of the hole, this annular cutter requires less power and time compared to traditional twist drills, resulting in faster and more accurate results for demanding projects.

Suitable for

• Professional metal fabrication and workshop tasks
• Industrial manufacturing and assembly operations
• Drilling clean and precise holes in structural steel and metal sheets
• Applications requiring high drilling accuracy and efficient chip removal

When it may not be suitable

This core drill bit is not intended for drilling non-metallic materials such as wood, plastics, or masonry. Additionally, it requires compatible magnetic core drilling machines or drill presses with appropriate arbors and is not designed for handheld portable drilling without a stable rig.

Key specifications

• Material: High-speed steel (HSS)
• Cutting diameter: 18 mm
• Cutting depth: 30 mm
• Tool type: Annular core drill bit

How to use

Secure the workpiece firmly to prevent any movement during the drilling process. Mount the Glob HSS core drill bit securely into a compatible magnetic drill press or milling machine using the correct arbor system. Align the pilot pin with your pre-marked center point to ensure precise hole placement. Apply a steady and consistent feed rate while utilizing adequate cutting fluid or lubricant to dissipate heat, reduce friction, and prolong the service life of the cutting edges. Clear away any accumulated metal chips before starting subsequent operations.

What to consider before purchase

• Verify that your drilling equipment is compatible with annular core drill bits of these dimensions
• Ensure you have a suitable pilot pin and cooling lubricant system available
• Check that the 18 mm diameter and 30 mm cutting depth match your specific project requirements

Always wear appropriate personal protective equipment, including safety glasses and gloves, and ensure the drill bit is securely fastened before initiating any metal cutting operations.
