Starrett 00429 Hole Saw 1 in 2 in Deep Hss

Product Description

The STARRETT 00429 is a high speed steel hole saw designed for cutting clean, round holes in metal, steel, and wood. With a 1-inch saw diameter and a 2-inch cutting depth, it handles both shallow and deeper through-cuts in a wide range of trade applications. The toothed cutting edge uses a variable pitch pattern with 4 to 6 teeth per inch, which reduces harmonics and chatter during the cut. This saw is a working tool intended for licensed tradespeople and experienced installers who need reliable, repeatable hole sizes in the field or shop.

This hole saw is suited for electrical, plumbing, HVAC, and general mechanical trade work where precise round penetrations are required. The 1-inch diameter is a common size for conduit knockouts, pipe penetrations, and access holes through wood framing, sheet metal, and light steel plate. At 2 inches of cutting depth, it passes through standard lumber, metal enclosures, and multi-layer assemblies without losing engagement.

Key Features

• 1-inch saw diameter for common conduit, pipe, and knockout applications
• 2-inch cutting depth handles framing lumber, metal enclosures, and stacked materials
• High speed steel construction for durability in metal and wood cutting
• Variable pitch toothed edge with 4 to 6 TPI reduces chatter and vibration
• Compatible with standard hole saw mandrels and arbors

Compatibility

Designed as an OEM-style replacement or direct-use hole saw for standard arbor-style mandrel systems used in trade cutting applications across metal, steel, and wood substrates.

Installation Notes

This hole saw is installed and used by electricians, plumbers, and HVAC technicians working with drill presses or handheld power drills. Always secure the workpiece before cutting and use appropriate cutting fluid when working through steel or hard metals to extend tooth life. Disconnect or de-energize any circuits or systems in the work area before cutting through panels or enclosures. Follow applicable NEC or trade-specific safety guidelines for hole-cutting in energized or pressurized systems.
