The Speedheater putty chisel with roller
Holding a plain chisel steady while you dig out old window putty is hard, and a slip means chipped glass or gouged wood. The Speedheater Chisel with Roller fixes that.
The roller sets the depth of the blade and moves the chisel forward smoothly along the thin wood muntin. Heat the putty with a Speedheater first, and the softened putty cuts away like butter, with the glass and the sash left intact.
Frequently asked questions
What is the Speedheater putty chisel used for?
It removes old window putty without chipping the glass or gouging the muntin. A roller controls how deep the blade cuts so you do not dig into the fragile wood, and the roller moves the chisel forward smoothly along thin muntins. After you heat the putty with a Speedheater, the softened putty cuts away cleanly with the glass and sash left intact.
How does the roller on the chisel work?
The roller sets the depth of the blade and rolls the chisel forward smoothly along the thin wood muntin. That keeps the chisel stable while you dig out putty, which a plain chisel makes hard to do. Controlling the depth this way is what prevents chipped glass and chewed-up wood from a slipping chisel.
How do you remove window putty with this chisel?
Heat the putty first with a Speedheater, then run the chisel along the sash. The Speedheater-softened putty cuts away like butter, and the roller controls the blade depth so the glass and wood stay intact. Without heating and depth control, a plain chisel slips and risks chipping glass or gouging the muntin.
