Starrett ST436EXRLZ Outside Micrometer Set

Starrett ST436EXRLZ Outside Micrometer Set - 0–12" Professional 12-Piece Set for Machine Shops & Quality Labs

When your shop needs to measure across a wide range of part sizes without reaching for a different tool every time, a matched micrometer set is the professional answer. The Starrett ST436EXRLZ gives you complete outside micrometer coverage from 0 to 12" in a single set - twelve precision instruments in 1" increments, each graduated to 0.0001", built on Starrett's 436 Series platform that machinists and QC professionals have trusted for decades.

At $6,126, this is a serious shop investment. It's also the kind of tooling that pays dividends every day - in faster setups, consistent inspection results, and the confidence that comes from measuring with instruments you can trust.

When your shop needs to measure across a wide range of part sizes without reaching for a different tool every time, a matched micrometer set is the professional answer. The Starrett ST436EXRLZ gives you complete outside micrometer coverage from 0 to 6" in a single set - six precision instruments, each calibrated to ±0.0001" accuracy, built on Starrett's 436 Series platform that machinists and QC professionals have trusted for decades.

At $6,126, this is a serious shop investment. It's also the kind of tooling that pays dividends every day - in faster setups, consistent inspection results, and the confidence that comes from measuring with instruments you can trust.

Who Needs This Set

• Machine shops running a variety of part sizes - a full 0–12" set eliminates the need to piece together individual micrometers over time
• Quality control labs requiring consistent, traceable measurement across multiple dimensional checks in a single inspection sequence
• Tool rooms & metrology departments that need a reliable, calibrated reference set for verifying other instruments
• Aerospace, automotive & defense manufacturers where dimensional accuracy is non-negotiable and instrument traceability is required
• Training & technical programs equipping students with a complete professional micrometer set for hands-on metrology instruction

Why a Matched Set Over Individual Micrometers

Buying individual micrometers from different batches or brands introduces subtle inconsistencies in feel, calibration, and wear characteristics. A matched set like the ST436EXRLZ ships as a coordinated group - same series, same manufacturing standards, same calibration baseline - so every instrument in your kit behaves the same way. For QC environments where repeatability matters, that consistency is worth more than the price difference.

Key Features

• Complete 0–12" coverage - twelve micrometers covering 1", 2", 3", 4", 5", 6", 7", 8", 9", 10", 11", and 12" ranges in one set
• 0.0001" graduation - read to the ten-thousandth of an inch with confidence
• Carbide-tipped measuring faces on both spindle and anvil - resists wear from repeated use on hardened workpieces; maintains accuracy far longer than standard steel faces
• Hardened steel frame - thermal stability and structural rigidity across the full measurement range
• Ratchet-stop thimble - consistent measuring force on every use eliminates operator-to-operator variability and allows quick adjustment
• Knurled ring-type lock nut - quick and certain spindle locking at any reading for referencing or transfer measurements
• Anvils sized at 0.250" diameter - designed for ease of use on larger work
• Satin-chrome finish - reduces glare under shop and lab lighting for easier reading and resists rust
• 11 micrometer standards included (1"–11") - for setting and verifying each instrument in the set
• Fitted storage case - protects all twelve instruments and standards, keeps the set organized and accessible
