Hole saw Abraboro HSS-Co bimetal 64 x 38 mm, model AB30064000

Abraboro HSS-Co bimetal hole saw 64 x 38 mm is designed for creating precise round openings in metal and a variety of construction materials. The bimetal construction combines high-speed steel with cobalt alloy to improve wear resistance and maintain cutting performance at elevated temperatures. The tool is intended for use with hand-held drills or drill presses and provides a cutting depth of 38 mm with a 64 mm diameter bore.

Advantages

The bimetal HSS-Co composition increases edge life and heat tolerance compared with standard high-speed steel, allowing sustained cutting in tougher materials. The 64 mm diameter and 38 mm cutting depth enable installation of medium-sized fixtures and conduits. The saw teeth geometry and robust body give a balance of cutting speed and durability suitable for repetitive trade use.

Suitable for

• Cutting through mild and alloy steels
• Creating openings for electrical boxes, conduit and pipe installations
• Sheet metal and thin-wall tubular work
• Use with portable drills and drill presses for through-holes

Key specifications

• Cutting diameter: 64 mm
• Cutting depth: 38 mm
• Material: bimetal high-speed steel with cobalt (HSS-Co)
• Intended mounting: compatible with standard arbors for hole saws
• Suitable for drilling speeds and feeds appropriate for HSS-Co tooling

How to use

Secure the hole saw to a compatible arbor and fasten it to the drill or drill press according to the machine manufacturer’s instructions. Mark the centre of the required opening and pilot-drill if needed to guide the saw. Operate at recommended speeds for HSS-Co cutters, apply steady pressure, and allow the tool to cut without forcing. Withdraw periodically to clear chips and, when cutting metals, use appropriate cutting fluid to reduce heat and extend tool life. After completion, deburr the hole as required.

Usage recommendations

For best results when cutting metals, use moderate spindle speeds, firm clamping of the workpiece, and suitable cutting lubricant. Replace the saw if tooth wear becomes pronounced to avoid damage to the workpiece and arbor.
