THE BORE GAUGES The bore gauges are used to measure internal sizes of work pieces by comparative method

GOOD GUIDING PROTECTIVE BRIDGE These series bore gauges are equipped with a good guiding protective bridge which can be self-centering exactly and reliably

Application – This kit universal fits for all diesel engines. Range: 1.00 inch. Graduations: .001 inch. Reading: 0-100.

Material – It is made of special high quality steel and aluminum alloy, hard coated crystal dial face for scratch & corrosion resistance, which reduces the weight of the product and has strong corrosion resistance, wear resistance and durability. Minimize measurement errors and make the measurement results more accurate.

Quick measurement steps – Cylinder sleeve height using pointed contact; Counter bore depth using flat end contact; Top dead center; Piston-to-deck height; Valve protrusion; Easy reading around entire bore.

This dial bore gauge set are equipped with a good guiding protective bridge which can be self-centering exactly and reliably

The moveable anvil on one side and an interchangeable on another side , which serves for setting the bore diameters

This dial indicator with magnetic base and point precision inspection set is measuring range is 50-160mm.Easy to measure, and with high accuracy, which is 0.01

Working Principle - Double action handles are rigidly attached to the contact plungers and are automatically self-centering.

Function - Assist in quick checking of holes, slots and recess up to 6 inch deep.

Scope of Application - Telescopic spring piston in the hole (or groove), can conduct inner diameter detection, used with micrometer or caliper, with knurled locking device.

Accurate Measurements: Used for accurately setting any bore gage up to 6" in diameter to an accuracy of 0.0001"; comes with a base anvil of 2.750" x 0.80" and 2 adjustable anvils of 2.375" x 0.375"

Bore Gage Capacity: This bore gage master has an internal capacity of 6", a depth capacity of 1", and a centralizer capacity width of 2.625"

Fast Adjustments: Features a quick-release holder for fast adjustment; this bore gage setting master can also be used of external setting, depending on the application (external mics, snap gages, caliper gages)
