Why this one
Mark the center so the drill does not walk (CP08, HMCH08A)
A step drill slides on a bare panel and a hole ends up off position. An 8 mm center punch makes the dimple, and the 8 oz claw hammer is the light strike that sets it.
Cut the round hole (TTSTD03)
A light head, speaker or grommet needs a clean round hole in sheet metal. The three step drills in a TT1 tray step up from 3 to 35 mm, so each drill cuts several hole sizes in steps without swapping to a hole saw.
Break the burr on both sides (TTNF12-02)
A burr left on the edge chafes a cable that passes through. The 160 mm half round needle file takes it off the front and the back of the hole.
Ease the hole to fit (FLRD10)
A hole that comes out slightly tight, or needs to be a little longer, has to be opened by hand. The 250 mm round file widens or elongates it to fit the fixture.
Read the full description
Every pass-through hole for a light head, siren speaker or cable grommet goes in the same order: mark, drill, deburr, file. This kit has a center punch and an 8 oz hammer to mark, a 3 piece step drill set from 3 to 35 mm to cut, and a round file and a needle file to finish the hole.
Bring a drill, and a grommet for every hole a cable passes through. Check the hole size in the light or siren maker's manual; the step drills run from 3 to 35 mm in steps.
In this bundle:
- 3 piece step drill set in a TT1 tray, 3 to 35 mm (TTSTD03)

- 160 mm half round needle file (TTNF12-02)
