Hole Saw (Bimetal HSS-Co) Abraboro 20 x 38 mm AB30020000

Abraboro Bimetal HSS‑Co hole saw 20 x 38 mm is a circular cutting tool intended for drilling precise round holes in thin and medium-thickness materials. Manufactured with a bimetal construction and HSS‑Co (cobalt alloy) teeth, the cutter is optimized to withstand higher temperatures and increased wear when working with metals, wood and plastics. Its 20 mm cutting diameter and 38 mm cutting depth make it suitable for common installation and workshop tasks when used with compatible arbors and drill drivers.

Advantages

The bimetal HSS‑Co construction provides improved heat resistance and longer edge life compared with standard HSS hole saws, allowing sustained cutting in tougher materials. The saw's tooth geometry and robust body deliver consistent hole quality and reduce the risk of jamming during through cuts. The 38 mm cutting depth accommodates thicker panels and allows clean openings for conduits and small pipe installations.

Suitable for

• Cutting holes in sheet metal, steel panels and non-ferrous metals
• Creating openings in wood and laminated boards
• Drilling holes in plastic and composite materials
• Installation of pipes, conduits and cable glands
• General workshop and maintenance drilling tasks

Key specifications

• Cutting diameter: 20 mm
• Cutting depth: 38 mm
• Material: bimetal with HSS‑Co (cobalt alloy) teeth
• Intended use: metal, wood, plastic
• Compatibility: for use with standard hole saw arbors and drill drivers

How to use

Mount the hole saw on a compatible arbor and secure it in the drill chuck. Mark the center point of the required hole and, if necessary, pilot-drill a small guide hole to stabilise the cutter. Use moderate drill speed and steady feed pressure; apply cutting lubricant when working with metal to reduce heat build-up and extend tool life. Withdraw periodically to clear chips and prevent clogging. After cutting, deburr the hole edge as needed.

Usage recommendations

For best results when cutting metal, use a cutting lubricant and operate at lower speeds with steady pressure. When drilling wood or plastic, higher speeds may be used but avoid excessive feed force. Inspect the arbor connection and tighten securely before each use. Replace the saw if teeth are visibly worn or damaged to ensure clean, accurate holes.
