SB-5 Carbide Burr 1/2″ x 1″ Cylindrical End Cut 1/4″ Shank Double Cut Die Grinder

SB-5 Cylindrical End Cut Carbide Burr – 1/2″ x 1″ (1/4″ Shank)

This listing is for a professional-grade SB-5 solid tungsten carbide burr. This tool is essential for any metal fabricator, welder, or machinist.

The SB-5 shape is cylindrical with cutting flutes on the end face. This critical design allows you to perform plunge cuts and bottom-facing inside of a slot, unlike standard “SA” burrs which only cut on the sides

Technical Specifications & Improvements

• Model: SB-5 (Cylindrical Shape with End Cut)

• Material: Solid Tungsten Carbide (Lasts 10x-20x longer than HSS bits).

• Cut: Double Cut (Cross-Cut) – The preferred cut for general-purpose work.

• Cutter Diameter: 1/2″ (0.500″)

• Length of Cut (Flute Length): 1″

• Shank Diameter: 1/4″ (0.250″) – Fits all standard die grinders.

Why Choose This Double-Cut Carbide Burr?

1. Double Cut (Cross Cut) Pattern: This burr features a double-cut pattern that produces fine, granular chips instead of long, stringy swarf. This results in:

• Smoother Finishes: Reduces gouging and pulling.

• Greater Control: Easier to handle on contoured surfaces.

• Wide Application: Ideal for harder materials like Steel, Stainless Steel, Cast Iron, and Titanium.

2. Solid Tungsten Carbide Material: Engineered for high-heat and high-speed applications. The solid carbide construction maintains extreme sharpness and will not soften or dull when used on hardened metals.

3. SB-5 End-Cut Design: The cutting flutes on the face of the burr allow you to mill the bottom of a slot or pocket flat, or plunge-cut into material like a drill bit.

Common Applications

• Welding: Removing weld beads and spatter.

• Deburring: Cleaning up sharp edges on freshly cut metal.

• Automotive: Cylinder head porting and engine block cleanup.

• Fabrication: Contouring and shaping hard metals.

• Sculpting: Ideal for carving steel and other hard materials.

Safety Warning: Always use this tool in a proper Die Grinder or heavy-duty rotary tool. Always wear ANSI-approved eye protection (face shield recommended) and gloves.
