Nk-8 - Cone Tungsten CARBIDE BURS Small 3/32 - HP Shank - NK8
3/32 Shank HP · CARBIDE CUTTERS
Overview
ATTRITOR NK-8 is Keystone's diamond-cut tungsten CARBIDE bur in the small-cone NK-8 head geometry, on a 3/32" HP-Shank for LAB straight handpieces. "Diamond-Cut" here refers to the criss-cross flute pattern on the CARBIDE blades — a flute geometry that gives faster bulk reduction and aggressive cutting on denture acrylic, gold and base metals. The name "Diamond-Cut" describes the flute design, not the bur material: the bur is solid tungsten CARBIDE throughout, not diamond-coated and not impregnated with diamond grit.
The ATTRITOR line is Keystone's premium CARBIDE tool brand for the dental LAB — tungsten-CARBIDE tool steel with diamond-cut flute geometry, designed for technicians who want faster acrylic and metal reduction without sacrificing tool life.
- NK-8 small-cone head shape. Sized for detailed contouring and tight-radius work on the LAB bench.
- Diamond-Cut flute geometry. Criss-cross blade pattern (NOT diamond material) — faster bulk reduction than plain-cut flutes.
- Tungsten CARBIDE construction. Solid CARBIDE throughout — 6–12× the tool life of high-speed steel.
- 3/32" HP Shank. Fits every LAB straight handpiece and bench-mount handpiece.
- Made in USA. Manufactured by Keystone Industries.
