Description
Product Overview
When you are sweeping a critical bore or tramming a milling head, any flex in your indicator base translates directly to scrapped parts. The BIG ACCU Magnetic Dial Indicator Base is a premium, heavy-duty layout tool designed to provide absolute, uncompromising rigidity for your most sensitive metrology tasks.
- The Larger Size Advantage: This is the larger variant of the ACCU base lineup. The increased mass of the articulated arms and the oversized magnetic base provide exceptional vibration dampening and maximum holding force, ensuring your indicator needle stays dead-steady even on large machine tools.
- Dovetail-Only Mounting: This specific model is purpose-built for lever-style Dial Test Indicators (DTIs). The clamping mechanism features a dovetail mount only (it does not have an 8mm stem hole). It provides a low-profile, ultra-rigid grip directly to the body of your test indicator.
- Micro-Fine Adjustment: Dialing in an indicator to absolute zero by tapping the arm is frustrating and time-consuming. This base features a highly precise fine-adjustment mechanism, allowing you to sweep your needle into position with buttery smooth, microscopic control.
- Heavy-Duty Magnet: Features a powerful, switchable permanent magnet base with a precision-ground V-groove, ensuring a massive holding force on flat machine tables or round drill press columns.
Condition
Used (Pristine Metal / Typical Knob Cracks).
This high-end magnetic base is in exceptional, pristine condition mechanically and structurally, with one very common cosmetic quirk.
- The Red Knob: In the spirit of total transparency, the red plastic locking knob exhibits the classic hairline stress cracks that are notoriously common to all used units of this specific model. However, the knob is still completely structurally sound, holding strong, and locking the arms down with rock-solid rigidity.
- Mechanical Integrity: The metal components, joints, and fine adjustment screw are pristine. The switchable magnet engages with a firm, uncompromising hold. It is completely ready to go to work.
