HSS Parting Holders Blades for Precision Lathe Cut-Off Operations

Parting holder blades are precision High Speed Steel (HSS) cutting blades designed for cut-off, parting, and grooving operations on manual and CNC metal lathes. These blades are manufactured to accurate width and thickness tolerances, allowing them to fit securely into compatible parting tool holders while delivering stable cutting performance. A sharp, properly ground blade produces clean cuts, reduces vibration, and improves surface finish, making it an essential cutting tool in every machine shop.

Buyohlic offers a complete range of parting holder blades for professional machining applications across the USA. Our collection includes HSS blades in multiple widths, lengths, and thicknesses to suit standard engine lathes, mini lathes, tool room lathes, and CNC turning centers. Every blade is precision-ground for dependable performance, accurate fit, and long service life.

Designed for Reliable Parting and Grooving

Parting holder blades are used whenever a finished component needs to be separated from bar stock or when a narrow groove must be machined to a precise width. During machining, the blade removes a narrow section of material while maintaining straight cutting action through the workpiece. Proper blade geometry helps produce consistent chips, lower cutting forces, and smoother cutting performance across different engineering materials.

These blades are commonly used for:

  • Parting finished components
  • Cut-off operations
  • Groove machining
  • Narrow slot cutting
  • Precision turning work
  • CNC production machining
  • Mini lathe applications
  • Tool room machining

Available Blade Sizes

Buyohlic supplies parting holder blades in several popular sizes, including:

  • 1/16" × 5/16" × 3½"
  • 3/32" × 1/2" × 4½"
  • 1/8" × 3/4" × 4"
  • 1/8" × 3/4" × 6"
  • 3/16" × 1" × 6"
  • 1.5 × 8.25 × 73 mm Mini Lathe HSS Blades

Multiple sizes allow machinists to choose the correct blade based on workpiece diameter, groove width, and machine capacity.

Choosing the Right Parting Holders Blade

Selecting the correct blade depends on the material being machined, the required groove width, and the diameter of the workpiece. Narrow blades require less cutting force and remove less material, making them suitable for smaller components and precision work. Wider blades provide greater rigidity during deeper cuts and heavier machining operations, helping reduce blade deflection on larger diameter workpieces.

Using the proper spindle speed, feed rate, and cutting fluid further improves blade performance while extending cutting life.

Frequently Asked Questions

Blade breakage is commonly caused by incorrect center height, excessive blade overhang, high spindle speed, insufficient lubrication, or interrupted cuts. Proper setup helps improve blade life.

The cutting edge should be set exactly at the lathe spindle centerline. Proper center height improves cutting performance, reduces chatter, and helps prevent blade dig-in.

Yes. Applying cutting oil directly to the cutting area helps reduce heat, improves chip evacuation, and extends blade life during manual lathe parting operations.

Fixed holders provide maximum rigidity for specific tool post sizes, while adjustable holders allow blade height adjustment for different machines and tool post configurations.

Blade size depends on the workpiece diameter and machining application. Narrow blades reduce material waste, while wider blades offer greater rigidity for larger workpieces and heavier cutting operations.
