SST Regular Mill & Lathe Tramming System - Precision Dial Tramming

In this review of the SST Regular Mill & Lathe Tramming System the bottom line is straightforward: this is a focused alignment tool for machinists and hobbyists who need to remove angular misalignment between a spindle and machine bed. The reviewer found it most valuable for setups where repeatable tramming and fine angular correction matter, thanks to its pair of SST dial indicators with 0.0005 resolution and a CMM-verified squareness system. It is not a general-purpose gauge but a purpose-built tramming system that prioritizes precision and durable materials.

Key Features

• High resolution indicators: Two SST dial indicators with 0.0005 resolution make it easy to spot tiny angular errors during setup and calibration.
• CMM-verified squareness: The squareness system was checked on a Coordinate Measurement Machine so users get verified geometry for accurate tramming.
• Solid construction: Machined from 6061 aluminum with a hard anodized finish for long life and resistance to workshop wear.
• Designed for angular misalignment: The tool focuses on correcting angular errors between spindle and bed to improve surface finish and part accuracy.
• Five-year warranty: Backed by a 5-year SST warranty that reduces ownership risk and supports long term use.

Who It's For

This tool is best for small shop machinists, CNC hobbyists, and professional users who frequently tram mills or lathes and need repeatable, high-resolution checks. It suits setups where angular misalignment is the dominant error and when users want a compact, purpose-built system rather than a broad measurement kit.

Users who primarily need rough alignment, general-purpose indicators, or complete dimensional metrology beyond tramming should look elsewhere. Also, those who cannot tolerate any shaft deformity should inspect the shaft on receipt, since some customers reported bent shafts in a minority of cases.

Pros & Cons

Pros

• Excellent sensitivity with 0.0005 resolution dial indicators for precise adjustments.
• Verified squareness and tight tolerances give confidence in the geometry during setup.
• Durable 6061 aluminum construction and hard anodized finish for long service life.
• Five-year SST warranty provides solid coverage and peace of mind.

Cons

• Not a full metrology system; purpose built for angular tramming only.
• A small number of customers reported bent shafts on arrival, so inspection at receipt is advised.
