Hole Saw for Metal MILWAUKEE A113MO10057 57 mm Bimetal

The MILWAUKEE bimetal hole saw 57 mm is designed for cutting circular openings in thin to medium-gauge metal sheets, pipes and similar workpieces. Made from bi-metal materials, this 57 mm hole saw combines cutting performance with heat resistance to maintain durability under repetitive drilling tasks. It fits standard hole saw arbors and can be used with hand drills and drill presses for mechanical, plumbing and installation jobs that require precise round holes in metal.

Advantages

This bimetal construction offers wear resistance and improved life compared with high-speed steel alone, while the 57 mm diameter meets common installation and maintenance requirements. The design supports efficient chip evacuation and reduced heat buildup, helping to preserve the cutting edges during continuous use. Compatibility with standard arbors makes the saw versatile across different drilling equipment.

Suitable for

• Cutting circular openings in thin and medium-gauge metal sheets
• Making holes in metal pipes and conduit
• Mechanical and HVAC installation tasks
• Electrical and plumbing service work requiring precise round holes

• Material: bimetal construction for durability and heat resistance
• Intended materials: thin to medium-gauge metals, metal pipes
• Compatibility: standard hole saw arbors for drills and drill presses
• Typical applications: mechanical, installation and maintenance drilling

How to use

Secure an appropriate arbor in the drill or drill press and attach the 57 mm hole saw according to the arbor manufacturer’s instructions. Mark the centre point on the workpiece and, if possible, use a pilot bit to stabilise the saw during the initial cut. Start drilling at low speed to establish the cut, then use moderate constant pressure and appropriate feed to avoid overheating. Periodically withdraw the saw to clear chips and allow cooling. Use cutting fluid or lubricant when working with thicker or harder metals to extend tool life.

Usage recommendations

Wear appropriate personal protective equipment, such as safety glasses and gloves. Select a drill or drill press with sufficient power and use a stable clamping method for the workpiece. For best results, use cutting lubricant on steel and stainless steel and allow the hole saw to cool between long cuts to maintain performance and prolong service life.
