Bore Micrometers - Free UK Delivery Over £25 - Buy Online | Zoro

(Individuals with Setting Rings)
Economical range of mechanical three point micrometers with XT (extended travel) feature on all models between 6 - 200mm capacity. This allows a wide measurement range without the need to change anvils. Both the measuring head and setting ring are UKAS calibrated (6 - 200mm range only). Blind bore measurements are available above 12.5mm. Tungsten carbide measuring faces on all 3-point heads from 12.5mm. (Micrometers with inch setting rings are available on request.)

3 point internal micrometers of sturdy construction are made highly durable with hardened alloy tipped contact points. Used for measuring deep holes with an extension rod which is available on models over 6mm measuring range. Accuracy: Instrument Error:	2-20mm		2 mu m, 	20-100mm	3 mu m, 		100-300mm	5 mu m. Each Holtest is supplied with hex-wrench.

The extended mechanical travel of these advanced two or three point gauges ensures that exchanging measuring anvils is now unnecessary. Their wide application range, 2-300mm, rugged construction and easy read scale, ensure both accuracy and ease of use. XT measuring heads and setting rings are supplied with UKAS certification.
