UF-SHARP Diamond Parting Tool for Wood Lathe

The UF-SHARP parting tool features a CBN-ground pre-sharpened edge, ready to use straight from the box. Its M2 cryogenically treated HSS construction provides 6- to 8-fold improvements in hardness and wear resistance, helping the tool hold a sharp edge longer. A longer beech wood handle offers a comfortable, non-slip grip for extended turning sessions, reducing fatigue during precise parting and grooving tasks.

Designed for thin kerf operation, the Robert Sorby 830SH offers precision in a slim profile. The tool extends 4-1/2 inches beyond the handle, with a 10-1/2 inch overall length and a 6 inch riveted ash handle for reliable control. The long reach supports deeper parting cuts while maintaining balance and reducing chatter through dense timber or intricate work.

This USA-made tool features a brazed carbide tip that remains secure during use and can be sharpened or blade replaced when dull. The tool comes with an interchangeable 17-inch handle system, bringing the total length to about 26.5 inches. It’s built for durability and can handle frequent parting, grooving, and fine detailing in home workshops or small shops.
High Speed Steel Parting Tool, 1/16″ Thick

The Sorby HSS parting tool features a hollow-ground edge for durability, with an edge that lasts longer than carbon steel options. The blade measures 6-1/2 inches in length and is 1/16 inch thick, providing a balanced combination of rigidity and responsiveness for parting cuts and shallow grooves on various woodturning projects.
LLDSIMEX Set of 2 8% Cobalt Parting Blades

These cobalt-based cut-off blades offer superior wear resistance and stability for demanding lathe tasks. The 8% cobalt content helps maintain a sharp edge during extended cutting and grooving. The blades are designed for parallel cutting and come in a practical 2-piece set to support routine replacement without downtime.

Buying Guide
Key considerations when selecting a parting tool for lathe work include material, edge retention, and ease of maintenance. Here are several perspectives to help you choose wisely:
- Material and edge retention: Carbide-tipped tools typically stay sharp longer than high-speed steel, reducing downtime for sharpening. Cryogenically treated HSS, like some UF-SHARP tools, offer enhanced wear resistance for frequent use.
- Tip replacement and sharpening: Tools with replaceable or easily sharpened tips save time in busy workshops. Brazed carbide tips are reliable but require proper alignment during replacement to prevent wobble.
- Handle design and ergonomics: A long, non-slip handle reduces fatigue during long turning sessions. Materials like beech or ash can provide a comfortable grip with good balance.
- Tool length and reach: Longer tools help with deep parting and greater leverage, especially on larger bowls. Shorter tools offer precision in tight spaces and control for fine cuts.
- Compatibility with lathe setup: Consider your spindle size, shank diameter, and available tool rests. Interchangeable handles can broaden compatibility with different tips.
- Support and warranty: When possible, choose brands with solid customer support and replacement parts. This helps maintain performance over time and protects your investment.
Across these options, users should weigh edge durability, maintenance requirements, and comfort to determine the best fit for their lathe work. Carbide-tipped tools are excellent for heavy workloads, while HSS variants and cobalt-tip blades offer a balance of cost and longevity. For hobbyists and professionals alike, a mix of tools can cover basic parting, grooving, and fine detailing.
