The Authority in Precision Thread Depth Gaging | Leitech US
COMBI Calibration Master
Calibrate your Leitech COMBI Gage for depth with the Calibration Master.
Simply dial in the thread pitch on the master, and calibrate the depth measuring scale.
Why Top American Manufacturers Standardize on Leitech
Over 30 years of helping Tier 1 Aerospace and Automotive shops eliminate "measurement lag" and reclaim machine capacity.
Slash Gage Inventory by 72%
The Problem: Traditional shops waste thousands of dollars on "static" gages—buying a new one for every single depth requirement. This ties up capital and clutters the quality lab.
The Leitech Solution: Because a single COMBI gage is adjustable across its entire range, it does the work of an entire drawer of conventional tools.
- Real-World Impact: One U.S. automotive plant used just 7 Leitech COMBI gages to inspect a 16-valve engine with 103 threaded holes.
- The Result: They eliminated the need for dozens of individual gages, reducing their total gage stock by 72%.
Cut Quality Control Time by 45%
The Problem: The "Two-Step" method (thread plug followed by a depth gage) is a production bottleneck. On high-hole-count parts like engine blocks or manifolds, those extra seconds add up to hours of lost time.
The Leitech Solution: Our "Single Operation" system verifies thread size and functional depth simultaneously.
- The Benchmark: In a head-to-head test on a complex V12 block (99 holes), conventional inspection took 71 minutes. * The Result: The Leitech COMBI finished the same part in 39 minutes—a 45% reduction in labor time.
Reclaim 17% of Your Machine Hours
The Problem: To "be safe," many shops drill and tap 15%–40% deeper than the blueprint requires. This "ghost depth" kills tool life and wastes expensive spindle time.
The Leitech Solution: Precision depth monitoring at the machine allows your operators to hit the exact spec every time—no more "guessing" and over-tapping.
- The Math: If you cut just 1.7mm deeper than necessary on 1,000 holes a day, you are wasting 374 meters (over 1,200 feet) of unnecessary threading per year.
- The Result: Our customers see an average of 17% savings in tool consumption and machine hours by hitting precise depths.
The Original. The Standard. The Future.
Our History
The authority in precision thread depth gaging for over 30 years, Leitech has been more than just a tool manufacturer—we are the architects of the thread depth gaging category. When we introduced the original COMBI system, we transformed inspection from a manual 'guesswork' process into a repeatable, NIST-traceable science.
Our Future
Today, Leitech U.S. continues that legacy of Danish innovation. While others have attempted to replicate our gages, they cannot replicate our precision. We remain dedicated to providing the automotive, aerospace, medical and defense industries with the 'One Tool, Dual Measurement' solutions that ensure absolute process control. When quality is non-negotiable, the industry turns to the original. The industry turns to Leitech.
