Product Overview
The KATSU Tools FIT-BAT 18V/21V Brushless Cordless Wood Router Trimmer Kit (SKU: 102755A) is a highly versatile, precision woodworking system engineered for edge trimming, mortise plunging, slot routing, and decorative joinery. Powered by a high-efficiency maintenance-free brushless motor delivering up to 30,000 RPM, this tool provides up to 2X extended battery runtime compared to traditional brushed motors. Featuring built-in LED work lights beneath the base and a 5-speed variable control dial (10,000 to 30,000 RPM), it ensures clear line-of-sight and optimal cutting control across softwoods, hardwoods, MDF, and laminates. This dual-base kit comes supplied with a heavy-duty Aluminium Plunge Base for deep routing and an ergonomic Plastic Protective Shield Base to prevent workpiece scratching. As part of the KATSU Tools FIT-BAT system, it offers broad power compatibility across standard 18V and 21V LXT-style lithium-ion platforms, fully equipped with 1/4", 6mm, and 8mm collets for immediate jobsite flexibility.

Laminate & Veneer Flush Trimming: Use the rubberized Plastic Protective Base for smooth flush trimming on plastic laminates and delicate veneers without surface marring.
-
Decorative Milling & Crafts: Creating clean bevels, decorative borders, and panel channels across softwood, hardwood, and MDF.
Operating & Care Guidelines
-
Incremental Pass Safety Guideline: To prevent motor overload and maintain precise tool control, depth of cut should not exceed 3mm per pass when cutting grooves. Make several passes with progressively deeper bit settings for cuts exceeding 3mm depth.
-
Notice on Soft Start: Please note that this specific cordless model does not feature soft start. Hold the tool securely with two hands when turning the power switch on.
-
Bit & Base Setup: Engage the spindle lock button, insert your router bit shank securely into the 1/4", 6mm, or 8mm collet, and tighten with the included wrench. Release the quick-clamp lever on the 64.8mm body to swap between the Plunge Base and Protective Base as needed.
