3/4" x 1-9/16" x 3/8" Radius Core Box Router Bit, 1-Flute, 1/4" Shank

Bosch Core Box Router Bit For Rounded Grooves

Bosch core box router bit with carbide tipped cutting edge is designed to cut rounded grooves, so it shapes clean channels needed in profiling work. The 3/4 inch core box profile establishes a wide, rounded-bottom groove that suits decorative and functional cuts in doors and columns. A 3/8 inch radius on the cutting edge forms a smooth curve at the bottom of the groove, which helps produce consistent profiles across long runs. The bit has a 1-9/16 inch cutting length that allows deeper groove cuts in a single pass where the setup permits, helping keep routing passes to a practical minimum. A single 1-flute cutting design engages the material with one cutting edge, which supports a steady feed feel and predictable chip ejection when routing typical woodworking materials.

Key Details That Support Routing Results

• The 3/4 inch core box profile produces a rounded-bottom groove that defines the overall channel width, which is important when matching design details across multiple doors or column faces.
• The 3/8 inch radius cutting edge shapes a consistent curved bottom in the groove, helping the finished profile read evenly when viewed along the length of the workpiece.
• The 1-9/16 inch cutting length provides capacity for relatively deep profiling passes, which lets the operator reach target groove depth without resorting to multiple different bits.
• Carbide tipped construction presents a hard cutting edge to the work, supporting clean cutting performance in typical wood-based materials used in doors and architectural columns.
• The 1/4 inch shank dimension fits routers that accept this shank size, giving the installer a direct way to select the bit based on the collet size on hand.
• The 1-flute design means one cutting edge is doing the work, which influences feed rate and chip flow in a way that many operators find predictable on standard routing passes.

Core Box Bit Sizing For Practical Setup

This 3/4 inch x 1-9/16 inch x 3/8 inch radius core box router bit uses clearly defined dimensions so the installer can plan the routing path relative to layout lines on doors or columns. The 3/4 inch sizing refers to the overall core box profile, aligning the groove width with panel and stile proportions. The 1-9/16 inch cutting length relates directly to the potential groove depth, which matters when routing deeper channels in thicker stock. The 3/8 inch radius describes the shape at the bottom of the groove, guiding how the routed profile will transition into surrounding flat surfaces. A 1/4 inch shank provides a known interface with routers designed around that shank size, simplifying selection when pulling bits for profiling work.

Using This Router Bit In Profiling Work

Where This Core Box Router Bit Is Applied

This Bosch router bit is specified for cutting rounded grooves used in a variety of applications ranging from doors to columns, so it fits directly into profiling tasks on architectural and cabinet components. When routed into door rails, stiles, or panels, the 3/4 inch core box shape forms decorative channels that can break up large flat surfaces. On columns, the same rounded groove can be repeated around the shaft to add visual structure or to define fluting-style details. Because the bit is carbide tipped, it suits woodworking environments where repeated routing in wood-based materials is part of normal door and column fabrication. The combination of core box profile and defined dimensions gives fabricators a consistent way to reproduce the same groove pattern across multiple matching components.

How Design Details Support Repeatable Grooves

The carbide tipped cutting edge on this core box router bit holds a defined profile, which helps each pass track the same rounded shape along doors and columns over time. With a 3/8 inch radius built into the bit, the operator does not have to shape the curve in multiple steps, so the bottom of the groove maintains a uniform arc from start to finish. The 1-9/16 inch cutting length allows the bit to engage more of the workpiece in a single plunge and pass, supporting efficient routing when deeper grooves are specified. A 3/4 inch core box profile sets the groove width mechanically, which keeps layout simple because the bit itself defines the final channel size. The 1/4 inch shank centralizes the cutting load through a common router interface, helping the bit track straight along guides or fences used during profiling.
