3 Wing Slotting Cutters For T Molding Work

3 wing slotting cutters give you a dedicated cutter for clean, consistent slots in woodworking projects where a precise groove matters. This Bosch carbide tipped slotting cutter is designed to make slots for T molding and weather stripping, so each pass shapes a groove that is ready to accept those profiles without extra cleanup. The cutter uses a 5/16 inch arbor, tying it directly to common arbor sizing and simplifying setup when you already run tools on that shaft size. Its 1/4 inch kerf establishes a fixed slot width, which keeps your groove sizing predictable from part to part. With three wings, the cutter spreads cutting forces across more teeth. That design supports smoother cutting action and practical strength in the cutter body during repeated slotting runs on typical woodworking materials.

Key Slotting Cutter Details For Woodworkers

• The Bosch carbide tipped construction focuses cutting on hard-wearing edges, which supports long service life when you repeatedly cut slots for T molding or weather stripping in shop environments.
• A 5/16 inch arbor configuration anchors the cutter to a defined shaft size, which helps you match the cutter to machines that accept that arbor and maintain stable running during slotting.
• The 1/4 inch kerf dimension fixes the slot width, which helps you produce grooves sized for uses that call for that cut, such as many T molding and weather stripping profiles.
• Three wings on the cutter body share the cutting load, which supports extra strength in the blade and helps maintain performance over extended use in joinery and slotting tasks.
• The design is used to make slots specifically for T molding and weather stripping, so the cutter geometry is aligned to those groove applications instead of general-purpose profiling.
• The Bosch designation BL85530M is used for biscuit joint cutting, showing that Bosch designs related carbide cutting tools for joinery tasks where controlled groove size matters.

Mounting And Slot Width Details For Setup

This Bosch 3 wing slotting cutter is built around a 5/16 inch arbor, so the mounting bore is sized for arbors of that diameter during installation on compatible equipment. Once installed, the cutter delivers a 1/4 inch kerf, meaning the material removed in the cut matches that width. That fixed kerf lets you tie machine setup, fence position, and passes to a known groove size when cutting for T molding or weather stripping. The three wing layout distributes force as the tool rotates, supporting stable tracking through the workpiece. Because it is carbide tipped, the cutting edges are formed from a hard material that stands up to repetitive contact with wood and similar materials in slotting operations.

Using The Bosch Slotting Cutter In Joinery

Where This Carbide Tipped Cutter Fits Best

This Bosch carbide tipped 3 wing slotting cutter fits applications where you need controlled slots for T molding or weather stripping in woodworking projects. Its role as a slotting cutter positions it within specialty saw blades, which focus on shaping specific grooves rather than broad ripping or crosscutting. The 1/4 inch kerf defines how much material the cutter removes, so it serves jobs that depend on that exact slot width, such as fitting T molding profiles designed for similar groove dimensions. The 5/16 inch arbor requirement ties it to machines that accept that shaft size, keeping the cutter centered and supported while cutting. In joiner blade roles, the three wing configuration adds strength to the cutter body and supports ongoing use for repetitive slotting in shop workflows.

Why These Slotting Details Support Consistent Results

The Bosch 3 wing slotting cutter uses its carbide tipped edges to hold cutting geometry over time, which supports slot size consistency run after run when making grooves for T molding or weather stripping. The 1/4 inch kerf ensures that once you dial in your fence and height, the resulting groove width remains tied to that measurement across panels and parts. With three wings, the cutter engages the workpiece more frequently per revolution, distributing load and supporting a steady feed feel that can help maintain alignment along the cut line. As a slotting cutter from the joiner blades class, it is built to focus on groove-making rather than general cutting, which suits repetitive joinery work. The reference to Bosch BL85530M for biscuit joint cutting shows that Bosch uses carbide-based tooling to handle other precise groove operations, underscoring the value of a fixed-kerf, purpose-built cutter when you need reliable slot dimensions for joinery tasks.
