Description
Product Overview
The Kanetec MB-EX28K High Lock Base is a precision magnetic indicator stand built for the toolroom and machine shop floor where a standard mag base simply won’t cut it. Designed around Kanetec’s “High Lock” clamping mechanism, this base delivers a significantly stronger and more repeatable hold than conventional on/off magnetic bases — keeping your dial indicator or test indicator planted exactly where you set it, even during interrupted cuts, heavy vibration, or extended setups. If you’ve ever had a standard mag base creep or slip mid-measurement on a surface grinder table or machining centre, you’ll understand immediately why this unit commands attention.
- High Lock magnetic clamping system — Kanetec’s High Lock mechanism generates a substantially higher clamping force compared to standard switchable mag bases. This matters when you’re holding position during runout checks on a rotating spindle or monitoring deflection across a long boring bar cycle — the base stays put without any drift in the articulated arm.
- Fine-adjust articulated arm with locking star knob — The yellow star knob (clearly visible and in good working order) locks the entire arm assembly in a single clamping action, allowing precise indicator positioning followed by a secure, rigid lock. No hunting for multiple screws — one knob, one motion, locked solid.
- Precision-ground magnetic base contact face — The base contact surface is ground flat to provide a reliable, repeatable seating surface on machine tables, surface plates, lathe beds, and chuck faces. A flat, accurate base contact is the foundation of any meaningful measurement — if the base rocks, the reading is noise.
- Compatibility — The MB-EX28K accepts standard 8mm diameter indicator stems (the near-universal standard for Mitutoyo, Starrett, and equivalent test and dial indicators). No adaptor required for most workshop indicators. Check your indicator stem diameter before purchase if using less common brands.
- Ideal for — Tramming a mill head, squaring a vice on a machining centre, runout checks on lathe chucks and mandrels, surface grinder table indicator setups, fixture alignment on a CMM surface plate, and any application demanding a rigid, vibration-resistant indicator hold.
Condition
Used (Good Condition / Clean Working Example)
This MB-EX28K presents as a genuinely solid used example. The magnetic base contact face shows the expected light bench patina from normal workshop use but no gouges, deep scoring, or raised burrs that would compromise seating on a ground surface. The articulated arm moves freely through its range of positions and locks down firmly with the star knob — no slop, no stick-slip in the joints. The High Lock on/off mechanism operates positively with a clean, deliberate action, and the magnetic holding force feels strong and consistent, as it should. The yellow star knob is intact with no cracking or stripping of the drive. The chrome-finished arm sections show minor handling marks consistent with regular use — nothing structural. Honest assessment: this is a tool that’s been used properly and looked after. The functional precision surfaces — the base contact face and the indicator stem clamp — are in good shape and ready for accurate work. As with any used precision holding device, we’d recommend a quick check of holding force on your specific machine table material before committing to a critical measurement run, simply as good practice.
