CLICK HERE: MICRO CASE TRIMMER INSTRUCTIONS
The Stainless Case Trimmer with Micrometer Adjustment is designed for precision reloaders who require exact control over case length. Built on Wilson’s proven inline trimmer platform, this model adds a micrometer adjustment system for fine tuning in .001 inch increments, allowing repeatable and measurable trimming results.
Precision Micrometer Adjustment System
This trimmer features a dual-adjustment system that combines coarse and fine control. The main stop screw is used for major length adjustments, while the micrometer allows precise incremental changes.
- Fine adjustment in .001 inch increments per marking
- Micrometer scale allows repeatable trim settings
- Clockwise adjustment shortens case length
- Counterclockwise adjustment increases case length
According to the instruction design, each micrometer marking represents a controlled change in trim length, making it ideal for load development and precision case preparation.
Inline Case Holder Design for Accuracy
Like all Wilson case trimmers, this tool uses a case holder that simulates a rifle chamber. The case is aligned by its body taper, ensuring proper positioning during trimming.
- Case holder system supports consistent alignment
- Stainless rail system guides cutter movement
- Produces square, uniform case mouths
- Reduces variation between cases
This inline design ensures dependable, accurate cuts from case to case, which is critical for consistent reloading performance.
Improved Design and Durability
This updated model includes several enhancements over previous versions:
- Stainless steel construction for corrosion resistance
- Expanded stop screw diameter for a more secure adjustment
- Wider stop nut for improved stability
- Black anodized crank handle for durability and smoother operation
These improvements provide a more stable trimming platform and longer service life for demanding reloading applications.
Versatile Case Preparation Tool
In addition to trimming, this tool can be expanded into a complete case prep system with additional accessories.
- Inside neck reaming
- Primer pocket crimp removal
- Case mouth deburring
This makes the trimmer a multi-purpose solution for reloaders looking to improve efficiency and consistency.
Setup and Operation
The trimmer can be mounted in a soft jaw vise or used with the Wilson Case Trimmer Stand for improved stability. The cutter is designed to operate in a clockwise direction and should be lubricated periodically for smooth performance.
- Compatible with power adapters (recommended 100–200 RPM)
- Adjust trim length using stop screw and micrometer
- Use case gages or calipers to verify final length
Caliber Compatibility
Trims cases from .17 to .45 caliber with the appropriate Wilson case holders (sold separately).
