Hole saw Abraboro HSS-Co bimetal 127 x 38 mm, model AB30127000

Abraboro bimetal HSS-Co hole saw 127 x 38 mm is a cutting tool engineered for creating precise circular holes in a range of metal materials. The bi-metal construction combines high-speed steel with cobalt reinforcement to improve wear resistance and maintain cutting performance at higher temperatures. The saw body and aggressive tooth geometry are intended for use in metalworking environments where durability and reliable hole quality are required.

Advantages

The HSS-Co bi-metal composition increases hardness and heat resistance compared with standard HSS, extending tool life during repeated cuts in steel and other alloys. The 127 mm diameter and 38 mm height provide a balance between cutting depth and stability, enabling clean, consistent holes with reduced chatter. The saw is compatible with common arbors and drilling machines, simplifying integration into existing workshop setups.

Suitable for

• Cutting circular holes in sheet metal and metal plates
• Creating openings in thin-walled pipes and tubing
• Metal fabrication and maintenance tasks requiring durable hole saws

Key specifications

• Cutting diameter: 127 mm
• Cutting depth (blade height): 38 mm
• Material: bi-metal high-speed steel with cobalt (HSS-Co)
• Tooth design: engineered for metal cutting and reduced vibration
• Compatibility: suitable for use with standard arbors and drill mounts

How to use

Secure the hole saw to a compatible arbor and mount it in a drill or drilling machine capable of providing steady rotational speed and torque. Mark the hole center on the workpiece, clamp the material firmly to prevent movement, and start drilling at low speed to establish the pilot position, then increase speed as appropriate for the material and saw diameter. Apply consistent feed pressure and use cutting fluid when working with steels or alloys to improve heat dissipation and prolong tool life. After cutting, remove burrs and inspect the hole for accuracy.

Usage recommendations

For best results when cutting steel and alloy materials, use suitable cutting lubricant, maintain moderate speeds to avoid overheating, and ensure the workpiece is securely clamped. Replace the saw if significant tooth wear or damage appears to maintain hole quality and operator safety.
