Overview

The Minerallac Company SKU 86229 is a 1-13/16" (45.24 mm) variable pitch bi-metal hole saw designed for efficient cutting across multiple materials. This combination drill and saw bit features a 5 teeth-per-inch (TPI) variable pitch design, engineered to cut 45% faster than conventional 6-pitch hole saws. The hole diameter measures 1.812" (46 mm) with a cutting depth of 1.5" (38.1 mm), making it suitable for applications requiring precise hole creation in wood, plastic, machinable metals, stainless steel alloys, and nail-embedded wood. This bi-metal construction combines high-speed steel teeth with a durable alloy body, providing extended tool life and resistance to heat buildup during prolonged use. The variable pitch design reduces vibration and improves chip clearance, resulting in cleaner cuts and reduced operator fatigue. The hex shank (7/16" standard) ensures compatibility with most drill drivers and hole saw arbors, including Minerallac's M24K and M45P models. Ideal for electricians, plumbers, HVAC technicians, and maintenance professionals, this hole saw excels in applications such as: - Electrical conduit installation (EMT, PVC, or rigid metal) - Plumbing pipe penetration through studs or joists - HVAC ductwork modifications - General fabrication and repair work The 86229 model is part of Minerallac's Cully series, a trusted brand in the electrical and mechanical trades. For optimal performance, use with a variable-speed drill at 1,200–1,800 RPM and apply steady pressure without forcing the cut. Compatible with standard 1/2" drill chucks when used with appropriate arbors.
