9/32" STRAIGHT BIT 1/4 SHANK, 85615M

Bosch 9/32 Straight Router Bit For Rabbets

Bosch 9/32 straight router bit gives cabinet shops and serious woodworkers a rabbeting solution sized for precise edge work on joints, drawer fronts, and similar applications. The bit uses premium-quality micrograin carbide tips that are ground on specialized CNC equipment, so the cutting edges deliver an extra-fine finish while maintaining maximum sharpness and edge retention across repeated passes. This router bit is identified as manufacturer part 85615M and is built on a fully hardened and tempered steel shank, which adds durability in demanding cabinet joinery work. Designed for cabinet joinery tasks, this Bosch router bit fits into cabinet workflows where consistent rabbeted edges are needed on panels and fronts. By combining a 9/32 cutting profile with a 1/4 shank, it aligns well with compact routers used around the shop or on the job.

Key Rabbeting Details That Support Joinery Work

• The bit is described as a rabbeting bit, so it cuts rabbeted edges for joints, drawer fronts, and other applications, which supports clean, repeatable joinery in cabinet construction and similar woodworking tasks.
• The router bit can be used for joining boards or for letting in back panels, allowing one tool to handle typical cabinet carcass joints and panel recesses without switching cutters, which can streamline setups.
• Premium-quality micrograin carbide tips provide superior wear resistance and long life, which helps the cutting edges stay sharper between sharpenings and maintain consistent cut quality across longer runs.
• The compact ball-bearing pilot guides the bit along the edge of the material, so the cut tracks the existing edge profile and helps maintain a consistent rabbet width without relying on external router guides.
• The control cut design helps minimize kickback during operation, giving the user more controlled entry into the cut and smoother feed, which supports safer, more predictable handling in the shop.

Rabbeting Bit Setup For Straight, Guided Cuts

This router bit is identified as a rabbeting bit for making rabbeting cuts without the use of a router guide, so the edge-following ball-bearing pilot handles guidance along the workpiece and keeps the rabbet path aligned with the board edge. The compact ball-bearing pilot guides the bit along the edge of the material, which helps maintain consistent shoulder location when cutting along drawer fronts, cabinet sides, or similar pieces. The fully hardened and tempered steel shank provides ultimate durability, so the shank holds up under normal routing loads while supporting the carbide cutting edges. With a 1/4 shank, this bit works in routers sized for that shank diameter, fitting common lighter-duty router setups used for detailed cabinet joinery operations.

Using This Bosch Router Bit In Cabinet Joinery

Where The Rabbeting Router Bit Fits Best

This Bosch router bit is specified as a rabbeting bit that cuts rabbeted edges for joints, drawer fronts, and other applications, so it fits naturally into cabinet joinery where shoulders and ledges are needed for assembly. When used for joining boards, the bit cuts consistent ledges that help boards register against each other, which can support square assemblies on cabinet cases and frames. The bit can also be used for letting in back panels, creating a recess that captures thin panels around the perimeter, which is a common requirement on cabinet backs and similar casework. The Web Description states that the bit works for these rabbeted edges and panel recesses, so it can serve as a go-to cutter for several core cabinet joinery operations in a single tool. The 9/32 straight cutting size works within smaller joinery dimensions, so it suits details on drawer fronts and comparable parts.

How Design Details Support Repeatable Results

The router bit features a compact ball-bearing pilot that guides the bit along the edge of the material, which keeps the rabbet cut following the existing edge and supports uniform shoulder spacing without external fences. The bit is described as designed for making rabbeting cuts without the use of a router guide, so its pilot-bearing guidance is intended to handle tracking on its own and help reduce setup steps when shifting between parts. Premium-quality micrograin carbide tips are ground on specialized CNC equipment for an extra-fine finish with maximum sharpness and edge retention, so the bit can deliver smooth rabbet surfaces that reduce sanding and keep dimensions more consistent across multiple passes. The fully hardened and tempered steel shank provides ultimate durability, supporting the carbide tips during cabinet joinery tasks and helping the bit stay stable at normal routing speeds. Together, these details support repeatable rabbet dimensions on joints, drawer fronts, and back panel recesses in cabinet work.

Common Questions About Bosch 85615M Rabbeting Use

Select This Bit For Focused Rabbeting Tasks

The Bosch 9/32 straight router bit with 1/4 shank and manufacturer part number 85615M is described as a rabbeting bit for rabbeted edges on joints, drawer fronts, and back panels, so it targets core cabinet joinery work.
