Sgs 91001 Spiral Downcut Router Bit 1/8 in Solid Carbide

Product Description

The SGS 91001 is a solid carbide spiral downcut router bit designed for precision routing in composite plastics and non-ferrous metals. With a 0.125 inch cutter diameter, a 0.5 inch length of cut, and a 1/4 inch shank diameter, this bit is built for tight-tolerance work where surface finish and edge quality matter. The downcut flute geometry pulls chips upward and presses the workpiece down, reducing surface tearout on the top face of the material. A 35-degree helix angle and bright uncoated finish make it well suited for clean, accurate cuts in soft metals and engineered composites. Woodworkers, CNC machinists, and fabricators working with laminates or aluminum sheet commonly reach for this profile.

This bit is intended for use in CNC router applications and handheld router setups where a 1/4 inch collet is used. Its square end geometry and right-hand cutting direction make it a standard choice for slotting, profiling, and edge work in composite plastic panels and non-ferrous sheet stock. The 2 inch overall length and 1.5 inch shank length provide adequate clearance for most light-duty routing operations without excessive overhang. It is well matched to production environments routing aluminum, phenolic, HDPE, or similar materials where a clean top surface is required.

Key Features

• Downcut flute geometry reduces tearout on the top face of the workpiece
• Solid carbide construction provides rigidity and wear resistance in non-ferrous and composite applications
• 35-degree helix angle for efficient chip evacuation
• Square end profile suits slotting, profiling, and full-depth passes
• Bright uncoated finish compatible with a wide range of non-ferrous and plastic materials
• Right-hand cutting direction for use in standard CNC and handheld routers

Compatibility

Compatible with routers and CNC spindles equipped with a 1/4 inch collet. Rated for composite plastics and non-ferrous metals per manufacturer material application data.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator familiar with router tooling. Ensure the router or spindle is fully powered down and locked out before changing bits. Seat the shank fully into the collet per the router manufacturer's minimum insertion depth requirements and tighten to the specified collet torque. Inspect the bit for chipping or wear before each use and replace if cutting edge integrity is compromised.
