## Summary description

Abraboro Otwornica BiM 140 mm is a bi-metal (BiM) hole saw with a 140 mm cutting diameter and 8% cobalt content.

## Long description

Abraboro Otwornica BiM 140 mm is a bi-metal hole saw with a 140 mm cutting diameter and 8% cobalt content, designed to cut round openings in metal and other demanding materials. The BiM construction combines a high-speed steel cutting edge with a flexible backing, while the added cobalt improves hardness and heat resistance for longer tool life when working on stainless steel, alloyed steels and other hard substrates. The hole saw is intended for use with standard drill drivers and drill presses and is suitable for trades where accurate circular cuts in metal are required.
Advantages
The 8% cobalt composition increases wear resistance and maintains cutting performance at elevated temperatures, reducing premature tooth wear during prolonged use. Bi-metal construction balances cutting-edge hardness with overall body toughness to resist breakage and deformation. The 140 mm diameter provides a large, consistent bore suitable for pipework, ducting and mounting applications. Designed for compatibility with common arbors and drill chucks, the tool offers straightforward installation and reliable centring for repeatable results.
Suitable for
 Cutting circular openings in stainless steel sheets and alloyed metals
 Creating holes for plumbing fixtures, pipe penetrations and flanges
 Preparing openings for HVAC ducts, vents and mounting plates
 Metalworking tasks on construction sites and in workshops
 Installation work requiring accurate large-diameter holes
Key specifications
 Cutting diameter: 140 mm
 Material: Bi-metal (high-speed steel teeth with flexible backing)
 Cobalt content: 8%
 Intended machine types: drill drivers and drill presses
 Primary application materials: stainless steel, alloyed steels and other hard metals
How to use
Mark the centre point of the required hole, mount an appropriate arbor and pilot drill, then secure the Abraboro BiM 140 mm hole saw to the arbor and tighten according to the arbor manufacturer's instructions. Use the drill at a controlled speed suitable for metal cutting, applying steady pressure and allowing the teeth to do the cutting. Use cutting lubricant or coolant when working on stainless steel or thick sections to reduce heat buildup and prolong tool life. After cutting, withdraw the tool and remove the slug, then deburr the edge of the hole as needed.
Usage recommendations
For best results when cutting stainless steel or other hard alloys, use a moderate cutting speed, steady feed rate and appropriate cutting fluid. Ensure secure workpiece clamping and a stable drill setup to maintain concentricity and reduce vibration. Inspect the teeth periodically and replace the hole saw if excessive wear or tooth damage is observed.
