Tuff Stuff 90004 Door Lock Kit
The Tuff Stuff 90004 is a bi-metal hole saw kit designed for installing door locks on both metal and wood doors. It suits professional locksmiths and DIYers who need a complete set for standard residential backsets. The kit includes two hole saws with an arbor and a two-sided self-centering jig. It handles door thicknesses of 1-3/8 inches and 1-3/4 inches.
Easy Installation With Guide Template
A supplied guide template enables exact drilling alignment for the lock bore and latch edge. The self-centering jig accommodates both 2-3/8 inch and 2-3/4 inch backsets without changing tools. Common issues arise if the door thickness falls outside the two specified sizes or if the drill speed is too high for metal cutting. Bi-metal teeth reduce binding but require steady pressure.
Bi-Metal Construction For Steel And Wood
The hole saws use bi-metal material to cut cleanly through steel and wood doors with the same blades. This single specification determines whether the kit matches the door material on the job. It will not suit doors thicker than 1-3/4 inches or backsets other than the two standard sizes listed. Buyers needing non-standard backsets or heavier commercial door prep should look elsewhere.

Questions about this item
How can I verify the hole saws are cutting cleanly through both metal and wood doors after setup?
The bi-metal hole saws should produce smooth, burr-free holes in steel and wood doors without wandering, and the self-centering jig keeps the pilot bit aligned for both 2-3/8" and 2-3/4" backsets.
What components come in the kit and what must I supply myself?
The kit includes two bi-metal hole saws with arbor and a two-sided self-centering jig for both backsets; you will need a compatible power drill and personal safety equipment.
Which version of the 90004 kit should I choose for standard residential door thicknesses?
The 90004 kit covers 1-3/8" and 1-3/4" thick doors with its included jig, so a single version handles both common residential thicknesses.
