Glob HSS Core Drill Bit 17 x 30 mm

The Glob HSS Core Drill Bit 17 x 30 mm is a professional-grade annular cutter designed for precise and efficient metal drilling applications. Manufactured from durable high-speed steel, this core drill bit delivers reliable performance, clean hole production, and extended operational lifespan when utilized in demanding workshop and industrial environments.

Advantages

Constructed from premium high-speed steel, the Glob HSS core drill bit offers exceptional durability and wear resistance during intensive metal cutting tasks. Its annular geometry allows for faster drilling speeds and reduced power consumption compared to traditional solid twist drills, as it only cuts the periphery of the hole. This design ensures clean, burr-free holes with accurate dimensions, minimizing the need for secondary finishing processes.

Suitable for

• Drilling structural steel and metal profiles in industrial fabrication
• Workshop metalworking and maintenance operations
• Creating precise holes for bolts, fasteners, and cable pass-throughs

When it may not be suitable

This core drill bit is not designed for drilling non-metallic materials such as wood, plastics, or masonry. Additionally, it requires compatible magnetic base drilling machines or specialized equipment and cannot be used efficiently with standard hand-held twist drill chucks.

Key specifications

• Bit type: HSS core drill bit / annular cutter
• Diameter: 17 mm
• Cutting depth: 30 mm
• Material: High-speed steel (HSS)

How to use

Secure the workpiece firmly to prevent any movement during the drilling process. Mount the core drill bit securely into a compatible magnetic drilling machine or drill press designed for annular cutters. Align the center pin with your marked drilling spot, apply appropriate cutting fluid to reduce friction and heat, and initiate drilling with a steady, moderate feed rate. Maintain consistent pressure throughout the cut to ensure optimal chip evacuation and prevent overheating of the cutting edges.

What to consider before purchase

• Verify that your drilling equipment is compatible with 17 x 30 mm annular cutters
• Ensure you have a suitable cooling or lubrication system available for metal drilling
• Confirm the required hole diameter and cutting depth match your project specifications

Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses and gloves, during metal drilling operations. Ensure proper alignment and use adequate cutting lubrication to maximize the lifespan of the high-speed steel cutting edges.
