Hole saw Abraboro HSS-CO 105 x 38 mm, bimetal (AB30105000)

Hole saw Abraboro HSS-CO 105 x 38 mm, bimetal is a precision cutting tool intended for creating circular openings in metal and a range of other materials. Manufactured from high-speed steel with added cobalt, the bimetal construction improves wear resistance and thermal stability for demanding drilling tasks. The tool has a cutting diameter of 105 mm and a cutting depth of 38 mm, making it suitable for creating larger-diameter holes with a single pass when used with compatible drills or drill presses.

Advantages

The Abraboro HSS-CO bimetal hole saw features a durable tooth geometry and cobalt-alloyed high-speed steel to resist edge wear and maintain cutting performance under elevated temperatures. Its 105 mm diameter and 38 mm cutting depth allow efficient removal of material in one operation, reducing the need for multiple passes. The bimetal construction provides a balance between toughness and hardness, improving tool life when working with steel, stainless steel, aluminum and other metals as well as some non-metallic materials.

Suitable for

• Cutting circular holes in sheet metal and metal plates
• Plumbing and HVAC installations requiring pipe and duct penetrations
• Electrical installations for cable entries and fixture mounting
• Metalworking tasks on drill presses and hand-held drills
• Fabrication tasks where a 105 mm diameter opening is required

Key specifications

• Material: high-speed steel with cobalt alloy (HSS-CO), bimetal construction
• Cutting diameter: 105 mm
• Cutting depth: 38 mm
• Suitable mounting: compatible with drills and drill presses using appropriate arbor or mandrel
• Typical applications: ferrous and non-ferrous metals, selected non-metallic materials

How to use

Secure the hole saw onto a suitable arbor or mandrel and clamp the workpiece to prevent movement. Mark the center of the desired hole and pilot-drill if necessary to guide the hole saw. Operate the drill at a speed appropriate for the workpiece material, apply steady feed pressure and avoid excessive side load. Use cutting lubricant when drilling ferrous materials to reduce heat and extend tool life. After cutting, remove any burrs from the edge of the hole with a deburring tool or file.

Usage recommendations

For best results, match drill speed to the material being cut and use cutting fluid on steel or stainless steel. Start with a pilot hole or use a guide to improve accuracy, and allow the tool to cool between extended cuts to preserve tooth hardness and geometry.
