Sgs Pro 16028 Inverted Cone Carbide Bur SN-41 Double Cut

Product Description

The SGS PRO 16028 is a double cut tungsten carbide inverted cone rotary bur conforming to industry specification SN-41. The cutting head measures 3/32 inch (0.0936 inch) in diameter with a 1/8 inch length of cut, mounted on a 1/8 inch diameter shank and measuring 1.5 inches overall. The double cut tooth pattern removes material faster than single cut and produces a smoother finish in a single pass. This bur is designed for use in die grinders, rotary tools, and pneumatic or electric handpieces by machinists, fabricators, tool-and-die workers, and maintenance professionals who need precise stock removal in tight or angled cavities.

The inverted cone geometry makes this bur well suited for undercutting, chamfering, and deburring recessed areas that straight or ball-nose profiles cannot reach. It performs on a broad range of metallic workpieces including carbon steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys. Typical applications include weld cleanup, port matching, mold finishing, and general deburring in production or repair environments. The 1/8 inch shank fits standard collets found on most bench-top and handheld rotary tools.

Key Features

• Tungsten carbide head for extended wear life on hard and abrasive metals
• Double cut flute pattern for fast material removal with reduced surface chatter
• Inverted cone (SN-41) profile designed for undercutting and angled cavity work
• Rated to 100,000 RPM for use with high-speed die grinders and rotary handpieces
• 10-degree included angle on the cone for precise engagement in tight profiles
• Uncoated head - no coating delamination risk on ferrous or non-ferrous substrates

Compatibility

Fits any die grinder, pneumatic handpiece, or rotary tool equipped with a standard 1/8 inch collet. Rated for use on steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys per manufacturer material application data.

Installation Notes

A licensed machinist or qualified fabricator should install and operate carbide burs. Secure the 1/8 inch shank fully into the collet before starting the tool - never run with a partially inserted shank. Always confirm the tool spindle speed does not exceed 100,000 RPM for this bur size. Wear ANSI-rated eye protection and appropriate hand protection; carbide chips and workpiece burrs are sharp and can be ejected at speed.
