Bore Gage

The best-selling range of bore gages now offers better accuracy, user-friendliness and durability.

All models are now more accurate
The measurement accuracy of new models has improved by 50% or more compared with their predecessors (in JIS standard values).

• Wide-range  accuracy: Improved from 5 µm to 2 µm
• Repeatability: Improved from 2 µm to 0.5 µm
• Adjacent error: Improved from 2 µm to 1 µm

33% longer plunger stroke

The plunger stroke of flagship models has expanded from 1.2mm to 1.6mm, still maintaining the stated accuracy.

Carbide contact tips and anvils

The new carbide-ball contact point and anvil tip have increased abrasion resistance compared with the steel-ball type and better surface roughness compared with the molded carbide-tip type. Thus, they almost never scratch a workpiece.

New grip improves accuracy during prolonged use

This model reduces the influence of heat from the operator’s hand by 50% by increasing the grip size and making the grip hollow-structured, thereby retaining high-accuracy measurement.

The length below the grip is the same as that of the old model. This guarantees no difference in the operability of the gage.

New contacts mean smoother action and better durability

Bore Gage Accessories (Options)

• Extension rods (optional) are available to assist in deep-hole measurement.
• When a rod is connected, there might be error margins due to the distortion of the rod, etc.In order to keep the error margins minimum, please don’t connect more than 2 rods to a bore gage.
• The maximum extension is limited to 1,000 mm.
• If using an extension rod longer than 500 mm, use the bore gage only in the vertical orientation
