Matework Adjustable Width Doweling Jig – Precision Woodworking Drill Guide with Imperial Scales

Overview

Meet the Matework Adjustable Width Doweling Jig, a precision drill guide designed for reliable dowel joinery across a range of stock. Crafted from durable anodized aluminum, the jig supports board thicknesses from 3/8" to 1-3/4" with a simple twist of the black handle to dial in the width. The combination of a front arrow marker and a side laser-etched imperial scale helps you locate the center and align holes with confidence, making straight, repeatable holes easier in everyday woodworking projects.

Designed for both professionals and DIYers, this tool pairs a robust build with practical features. The hardened surface (HV 300-500) adds wear and corrosion resistance, while thermally stable construction keeps up with the demands of real-world shop usage. The kit is ready for a variety of joinery tasks, from small edge joints to larger shelf, cabinet, table, or railing projects, without sacrificing precision.

Key features at a glance

• Adjustable width enables drilling across multiple stock thicknesses (3/8"–1-3/4").
• Front arrow marker and laser-etched imperial scale aid center location for accurate hole placement.
• High-quality anodized aluminum body delivers durability and resistance to wear and corrosion.
• Versatile joinery tool for T-, L-, edge, and offset joints across shelves, cabinets, and furniture.
• Kit includes 3 drill bits and 3 stop rings for immediate setup on varied projects.

Practical use cases

In a workshop setting, you can build sturdy shelves or cabinets with evenly spaced dowel joints, ensuring clean edges and tight alignments. The crisp center markers help you establish repeatable hole patterns on multiple pieces, while the adjustable width accommodates differing stock without swapping guides. The result is consistent joint alignment with less guesswork, whether you’re assembling a floating desk or adding a railing.

Real-world projects benefit from the kit’s ready-to-use drill bits and stop rings, which streamline setup for routine tasks and enable you to tackle more ambitious builds without pausing to source extra hardware.

How to get the best results

• Setup: insert the bit into the drill guide until it touches the workpiece, withdraw about 1/4" (6 mm), then start at full speed and feed smoothly.
• For pocket-style drilling, partially withdraw the bit several times to eject shavings, reduce heat buildup, and extend bit life.
