Description
Product Overview
Setting precise angular relationships between a workpiece and your machine — whether you’re dressing a grinding wheel to a specific helix, presenting stock to a surface grinder at an odd angle, or dialling in a compound setup on the lathe — normally means stacking sine bars, shimming blocks, and hoping nothing shifts when you tighten the clamp. The Kanetsu KM-08W solves that problem directly: two heavy-duty magnetic V-blocks joined by a calibrated radial adjuster that lets you set and lock an exact angular relationship between the two contact faces, reading directly off a graduated dial, no trig tables required. This is a used unit in fair condition with honest wear to the cosmetics but solid mechanical function in the adjuster mechanism.
- Calibrated radial adjuster with graduated dial (0–180°): The central dial mechanism allows you to set the angular offset between the two V-block faces with a readable graduation — critical when you need a repeatable angle for batch work or when matching a compound angle on a second op without re-indicating from scratch.
- Twin magnetic V-blocks as the contact faces: Both blocks are ground V-profile magnetic units, meaning they grip round or square stock positively and hold it without clamps interfering with your setup. The magnetic hold keeps the workpiece registered while the angular relationship is dialled in and locked.
- Rigid cast body construction: The unit is built with enough mass and rigidity that once the angle is set and locked, it doesn’t spring or creep — important on a surface grinder table or when transferring a setup from bench to machine.
- Kanetsu Kogyo manufacture, Japan: Produced by a Japanese precision tooling manufacturer with a long history in magnetic workholding — the same country of origin credibility you’d associate with Mitutoyo or Sugatsune-grade toolroom hardware.
- Ideal for: Surface grinder angular setups, presenting round stock at compound angles for milling, dressing operations requiring a precise helix or lead angle, angular inspection tasks on a surface plate, and setting up sine-style relationships without building a sine bar stack.
Condition
Used (Fair Condition / Cosmetic wear, mechanically functional)
The two V-block faces show the dark patina and surface wear consistent with genuine shop-floor use — expect minor marks, light scoring, and the kind of honest wear you see on a tool that’s done real work. The body finish on both blocks is worn in places and there is visible surface oxidation to the metalwork, consistent with storage rather than active abuse. Importantly, the radial adjuster mechanism rotates and the locking action engages — the dial is legible across its full 0–180° graduation range. The ground V-faces retain their functional geometry; this isn’t a tool where cosmetic wear compromises the contact surfaces in a way that would introduce meaningful angular error for typical workshop use. That said, for any precision application — particularly if you’re working to better than half a degree — we’d recommend verifying the zero datum of the adjuster against a known square reference before committing to critical work. The magnetic function of both blocks should be confirmed by the buyer on receipt as standard practice with any used magnetic tooling.
Included:
- 1 x Kanetsu KM-08W Magnetic V-Block Angular Adjuster (twin V-blocks joined by radial angle adjuster)
Not included: Original case or storage box, documentation or calibration certificate.
Brand Information
Kanetsu Kogyo Co., Ltd. is a Japanese manufacturer specialising in magnetic workholding and precision tooling, headquartered in Japan and producing equipment used in toolrooms and production environments across Asia, Europe, and Australia. The brand sits in the same tier as other respected Japanese precision tooling names — credible, accurate, and built to a standard that reflects Japan’s long-standing reputation for disciplined manufacturing tolerances in metrology and workholding equipment. Kanetsu magnetic chucks and blocks are found in surface grinding shops and toolrooms where magnetic workholding is taken seriously, and their angular V-block products like the KM-08W represent a practical, purpose-built solution rather than a general-purpose bodge.
