Key Features
Overview
The Klein Tools Bi-Metal Hole Saw, 2-Inch (31019) cuts precise 2" (5.1 cm) holes in stainless steel, mild steel, drywall, ceiling tile, laminates, wood and plastic. This is a bi-metal hole saw designed for electrical, mechanical and general construction work where one cutter has to handle metal and softer materials alike.
At 2" (5.1 cm), the diameter and the 2" (5.1 cm) cutting depth are the same, which makes this an easy size to plan around. The saw weighs 4.6 oz (130 g).
The 2" (31019) cutting edge is bi-metal, tuned for steel first, and it carries Klein's VARI-RAKER ET 4/6 TPI variable tooth pattern. That combination is what lets one cup move from stainless and mild steel to wood, laminate and drywall without swapping to a different saw.
Klein put real thought into plug removal on the 31019. The cup wall has a unique pattern of access slots that give you both clearance and leverage, which turns a stuck plug into a quick push with a flat screwdriver.
Durability starts at the back plate, and Klein makes the 2" saw's back plate thicker than standard to take abuse. Mounting is flexible: the saw is compatible with Klein's quick-release arbor and with traditional threaded arbors. An arbor is required and sold separately.
Nearby Klein bi-metal hole saw sizes include the 1-3/4" (31018) and 2-1/8" (31020), if your layout calls for a different diameter.
Who should buy it: trades that cut through mixed materials in a day, from steel boxes and panels to framing and drywall, and anyone adding a 2" size to a hole saw kit that has to hold up in metal.
