SLIIMU Floating Shelf Dowel Jig Kit — Straight Hole Drill Guide with 1/2 Inch x 9.8 Inch and 1/2 Inch x 5 Inch Bits

Overview

Introducing the SLIIMU Floating Shelf Dowel Jig Kit, a precision-focused tool designed to support hidden shelf brackets and mantles. The kit blends rigidity with manageable weight through an industrial-grade aluminum alloy body, a hardened steel drill sleeve, and a vibrant anodized orange finish that resists wear while keeping the setup visually clear in busy workspaces.

The centerpiece is a 1/2 inch centered straight hole design that self-centers to keep drills true. This alignment helps maintain clean aesthetics on edge detailing and reduces the risk of angled drilling on live-edge boards or decorative panels.

• Two high-speed drill bits: 9.8-inch and 5-inch, suitable for wood up to 2.8 inches thick
• Self-centering dowel guide to locate the center before drilling
• mounting hardware to secure the jig during setup

Usage and applicability

• Ideal for quick installation of hidden mantel or shelf brackets
• Designed to help ensure a centered, straight hole for invisible shelf hardware

How to use

• Twist the jig to find the centered drilling location
