TESA management recently discontinued production of its Brown & Sharpe Standard bore and snap gages. Mahr Federal bore and snap gages are available to replace these TESA products. They allow users to upgrade performance with integrated wireless data transmission. Replacement gages include Mahr Federal 1280 P and 844 N adjustable bore gages, along with 300 P snap gages.
Mahr Federal 1280 P adjustable bore gages feature rugged construction for long life and low maintenance, including a stainless steel gaging head and one piece centralizing yoke with replaceable tungsten carbide balls. Furnished with either a dial or digital indicator and available with integrated wireless data transmitters, 1280 P bore gages are sized to measure diameters from 12 — 200mm (0.50 — 8") with extensions, and depths from 76 — 1220mm (3 — 48").
Also available with integrated wireless transmission, Mahr Federal's precision self-centering 844 N adjustable bore gages are virtually impervious to temperature changes as both the shank and transfer rod are made from Invar steel. Extremely versatile and quick to adjust to any size within their range, 844 N bore gages can be used to measure diameter, roundness, and conical form, as well as the distances of plane-parallel surfaces of tight tolerance parts. Able to measure diameters from 18 — 800mm (0.7 — 32"), they provide low hysteresis and high repeatability.
Mahr Federal 300 P snap gages provide fast precise OD measurement on the shop floor. Available over a wide range of sizes, styles and readout configurations, they provide measuring capacity from 0 — 508mm (0 — 20") and are available with integrated wireless transmitters and dial or digital indicators. A unique "Channel Lock" design assures precisely parallel anvil surfaces, with positive position locking at any point within the range.

- outer diameter ( OD)
outer diameter ( OD)
Dimension that defines the exterior diameter of a cylindrical or round part. See ID, inner diameter.
- parallel
parallel
Strip or block of precision-ground stock used to elevate a workpiece, while keeping it parallel to the worktable, to prevent cutter/table contact.
- shank
shank
Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.
- tolerance
tolerance
Minimum and maximum amount a workpiece dimension is allowed to vary from a set standard and still be acceptable.
- tungsten carbide ( WC)
tungsten carbide ( WC)
Intermetallic compound consisting of equal parts, by atomic weight, of tungsten and carbon. Sometimes tungsten carbide is used in reference to the cemented tungsten carbide material with cobalt added and/or with titanium carbide or tantalum carbide added. Thus, the tungsten carbide may be used to refer to pure tungsten carbide as well as co-bonded tungsten carbide, which may or may not contain added titanium carbide and/or tantalum carbide.
