Description

The ATTRITOR NK-Series is a numbered range of tungsten-CARBIDE laboratory BURS (NK-1 through NK-8) on HP Shank (3/32" / 2.35 mm) for laboratory bench-handpiece use. Each NK number represents a specific cylinder geometry — flat-end, round-end, taper — at a specific cut grade, identified by Q-series MfgItemNumber (Q023, Q0235CE, Q0235FE, etc.).

  • HP Shank (3/32" / 2.35 mm) — laboratory bench handpiece use
  • Tungsten CARBIDE with Diamond-Cut flute pattern
  • NK-1 through NK-8 sequential geometry numbering
  • Q-series MfgItemNumber denotes specific cylinder shape and cut grade
  • Color-coded by cut grade (GREEN/BLUE) for fast bench identification
Why You'll Love It
Diamond-Cut flute pattern resists load-up on tough LAB substrates.
Sequential NK numbering — pick the NK number that matches your geometry need.
HP-Shank fits any standard laboratory bench handpiece.
Color-coded by cut grade — fast bench-side identification.

If You Are Looking For…

Flat-end cylinder bur for acrylic surface work: Use NK-1 Cylinder Flat End at the matching cut grade.
Round-end cylinder bur for acrylic contour work: Use NK-4 Cylinder Round End.
Coarse cut for bulk acrylic removal: Use the Coarse (GREEN) cut grade at your shape.

Materials & Construction

Cutting media: tungsten CARBIDE with Diamond-Cut flute pattern.

Operating Speed & Use Guidance

Operate at the laboratory bench handpiece's rated RPM — typically 20,000–35,000 RPM for HP-Shank CARBIDE.

Light, controlled pressure — Diamond-Cut flutes work best at moderate feed rate.

Sterilization & Handling

  • Autoclavable per the manufacturer's protocol
  • Pre-clean substrate residue from the CARBIDE flutes before sterilization
