Description
Door Lock Installation Kit, Door Knob Installation Kit with Hole Saws for Wood Doors
-
No guesswork on hole placement: the backset markings for 2-3/8 and 2-3/4 inch line up in seconds
-
One guide, four fast steps: position, bore, drill the latch, then fit the lockset and test it
-
Built for real wood doors: bedroom, bathroom, closet, and rental-property doors all take the same door lock jig
-
Cut clean through wood-based material: solid wood, plywood, particle board, and drywall all cut cleanly with the included saws
-
Room to go further: the expanded kit adds a mortising jig, router bit, and hex key for detailed installs
Installing a new door lock without the right guide usually means crooked bores and a scarred door face, but this door lock installation kit lines up every cut before the drill even touches the wood. The adjustable plastic guide clamps onto the door, and the marked backset positions match the two sizes almost every interior door uses, so the hole saw goes in exactly where it should the first time. It is built for wood: the guide and hole saws are made for solid wood, plywood, particle board, and drywall doors, not glass, tile, or metal ones.
The standard hole saw set covers the main bore and the latch hole in one pass, and the expanded configuration adds a mortising jig, router bit, and hex key for hinges and strike plates on bigger door-hardware projects — a power drill and mounting screws are the only things you still need to bring.

Key Features

Kit Configurations: Standard red or yellow kits pack one adjustable plastic guide, a 2-1/8-inch (54 mm) main hole saw, a 1-inch (25 mm) latch hole saw, and a pilot-bit arbor, while the expanded set adds a metal mortising jig, extension holder, screwdriver bit, router bit, and hex key for deeper installs; a power drill and mounting screws are not included.
-
Four-Step Installation: Secure the guide to the door, bore the main hole halfway from each side, cut the latch hole from the side opening, then fit the latch and lockset and test it.
-
Built For Wood Doors: The template suits bedroom, bathroom, closet, utility-room, and rental-property doors, replacing old locks or adding new knobs on interior wood doors only.
-
Marked Backset Positions: Guide markings match common 2-3/8-inch and 2-3/4-inch backsets, so you measure the door and backset, line up the marking, and confirm the fit before drilling.
-
Cutting Range: The hole saws cut solid wood, plywood, particle board, and drywall, but skip glass, tile, granite, metal, brick, stone, stainless steel, and other hard or fragile surfaces.
