Value Collection 399-1136 Three Square Finishing Stick

Product Description

The VALUE COLLECTION 399-1136 is a three square toolroom finishing stick designed for precision deburring, honing, and surface finishing of dies, molds, and toolroom workpieces. Shaped with three flat faces meeting at sharp corners, this stick reaches into internal angles, slots, and recesses that flat or round sticks cannot access. It measures 4 inches long by 3/8 inch wide and is manufactured from silicon carbide abrasive in a medium grade. Silicon carbide cuts hard materials efficiently, making this stick well suited for hardened tool steels, carbides, ceramics, and cast iron. At 0.1 pounds, it is lightweight enough for extended handheld use during bench work.

This finishing stick is intended for use in toolroom, die shop, and maintenance machining environments. Machinists, tool and die makers, and maintenance technicians use it to remove burrs, blend parting lines, and achieve consistent surface finishes on precision components. The three square profile is particularly effective for cleaning up internal corners on stamping dies, injection mold cavities, and broach guides where a flat stick would rock and lose contact. It is used dry or with a light cutting fluid depending on the material and finish requirement.

Key Features

• Three square profile reaches internal corners and angular recesses inaccessible to flat or round sticks
• Silicon carbide abrasive cuts hard ferrous and non-ferrous materials including hardened steels and carbide
• Medium grade provides a balance between stock removal and surface finish quality
• Compact 4 inch length suits handheld bench use and close-quarters deburring
• Black silicon carbide construction visible against most workpiece materials for easy positioning
• Lightweight at 0.1 pounds for extended use without fatigue

Compatibility

Designed as a general-purpose toolroom finishing stick suitable for hand deburring and honing operations on hardened steels, cast iron, ceramics, and similar hard materials in die shop and maintenance machining applications.

Installation Notes

This abrasive stick is used by hand or in a holder during bench machining and finishing operations. Secure the workpiece in a vise or fixture before working to prevent movement and maintain consistent contact angle. Wear safety glasses and protective gloves, as silicon carbide particles and metal burrs present a laceration and eye hazard. Use light, consistent strokes and inspect the stick periodically for loading or glazing, which reduces cutting efficiency.
