Cle-Line C25051 M42 Bi-Metal Hole Saw
The Cle-Line C25051 is an M42 bi-metal hole saw designed for drilling large-diameter holes in metal, wood and plastic. It suits professional tradespeople and serious DIY users who need a durable cutting tool for occasional or repetitive workshop tasks. The bi-metal construction resists heat and wear during extended use. Supplied as a single saw without an arbor.
Suited for M42 bi-metal cutting, not carbide grit
This hole saw suits users cutting mild steel, stainless steel, aluminium, wood or plastic where an M42 bi-metal edge is specified. It is not for buyers who need carbide-grit or diamond-grit edges for abrasive materials such as tile, stone or cast iron. Users requiring a complete kit with arbors and pilot drills should look at a dedicated set.
111 mm cutting diameter matches 4-3/8 inch spec
The saw cuts a 111 mm diameter hole, matching the stated 4-3/8 inch size. This single dimension decides whether the tool fits the required hole size for pipe, conduit or hardware installations. Verify the target diameter before purchase as no other sizes are included.

Questions about this item
When will the M42 bi-metal teeth on the 111 mm hole saw need replacement?
The M42 bi-metal edge resists wear longer than standard steel, but replacement depends on how often you cut metal and the feed pressure you apply.
What limit appears first when the 4-3/8 inch saw runs continuously in thick plate?
Heat buildup in the cutting zone typically becomes the limiting factor before the arbor or shank shows stress.
How much noise and heat does the 1887 model generate during all-day use?
Expect normal hole-saw vibration and audible cutting noise; the bi-metal body dissipates heat steadily, so the tool stays warm rather than hot.
