Microjig MatchFit Relief Bit 1/4 Shank – Pre-Routing for Precise Dovetail Grooves

Precision and longevity for MatchFit-driven projects

In a busy workshop, clean grooves and durable tooling matter as much as design flair. The Microjig MatchFit Relief Bit is engineered to pre-cut waste, setting you up for smoother dovetail grooves and longer tool life. This bit isn’t just an accessory—it’s a key piece in the MatchFit ecosystem that helps you build reliable jigs, fixtures, and workholding with less guesswork.

By tackling waste early, you can protect your dovetail bit and your router, while keeping the focus on accuracy and finish. The depth is easy to dial in, and the groove finish stays tidy enough to reduce sanding time between passes, helping you move from setup to finished piece more confidently.

Notable advantages at a glance

• Efficient Waste Removal: Removes about 55% of waste material before routing dovetail grooves, significantly reducing strain on your router and bits.
• Precision Depth Control: Laser-etched depth guide for quick, accurate cutting depth adjustments and improved repeatability.
• Smooth Groove Finish: Built-in roundover smooths the top shoulders of the groove, preventing tear-out and reducing sanding time.
• Extended Tool Life: Relieves stress on your dovetail router bit, prolonging its lifespan and ensuring consistent performance.
• Versatile Compatibility: Available in 1/2" and 1/4" shank sizes, suitable for a range of routers and materials including plywood and MDF.

Design and performance you can feel

The relief bit uses high-quality carbide with a 3-degree up shear for efficient material removal. An extra-wide shoulder helps minimize vibration and noise, contributing to a smoother cut line. The bright yellow body makes it easy to identify in a crowded tool chest, while a laser-etched depth guide supports quick, repeatable depth settings. For best results, run at around 14,000–15,000 RPM and keep the motion steady to avoid heat buildup.

Why it fits the MatchFit system

Pairing this bit with MatchFit clamps and tracks unlocks flexibility to build consistent jigs, fixtures, and sleds. The relief bit reduces initial load on the dovetail bit, potentially extending its life and helping you maintain cutting quality as you scale up projects.

Real-world use cases

Imagine routing the initial grooves for a new dovetail track, then following with the MatchFit dovetail bit for the final passes. The relief bit’s pre-cut waste and smooth shoulders translate to fewer sanding steps and a cleaner finish across stock such as plywood or MDF.

Usage tips

• Keep the router moving to minimize heat buildup and ensure a clean pass.
• Use the laser depth guide to verify depth before each cut for repeatable results.
