Listed specifications

Where this cutter fits

TSC12 is listed as a straight slot cutter for narrow grooves, slots and panel or furniture joinery where the finished width must match a drawing or mating part. Select the cutter by the required 3 mm width, then verify the shank and the way the workpiece will be guided.

Guide and setup checks

• The listing identifies a bearing guide, so check the guide position and clearance against the workpiece before routing.
• Confirm that the router or spindle accepts a 1/4 inch shank and that the collet can hold it with the required engagement.
• Check the planned groove depth, material support and cutter clearance. A narrow cutter should not be forced through an unnecessarily deep pass.
• Make a test cut in matching scrap and measure the slot before routing the finished panel or component.

Choosing between nearby TSC models

The TSC series includes several widths and guide arrangements. Use the dimension on the project drawing rather than the model number alone. A 3 mm cutter is not a substitute for a different width, even when the shank and tooth count match. For the next size or the bearing-guided version, compare the listings in the T-Slot Cutters category.

Before you order

Send the product link or model, router or spindle model, collet size, material, target groove width and quantity to sales@bitsrouter.com if you need a fit check. The ordering help guide explains what information to include. Use the machine and tool supplier’s limits for speed, feed, guarding and cutting depth.
