The Cogsdill Micro-Limit is a precision depth-control countersinking tool designed for rugged production work. It consists of a drive featuring a piloted countersink and a depth-control adjustment mechanism. The tool is engineered to deliver accurate and consistent results from part to part by pre-setting the desired depth of cut, which is locked in place. During operation, the pilot engages in the hole while a hardened steel stop collar seats on the face of the workpiece, allowing the tool to advance and countersink the hole to the exact depth required.
Available drive models include ML-200, ML-300, ML-300-OT, ML-400, and ML-400-OT.
- Precision Depth Control: Depth adjustment is performed in increments of .001 inch (.025 mm) by hand-indexing the castellated adjustment collar.
- Rugged Construction: Built for high-production applications with thrust loads taken up on ball bearings through a hardened steel stop collar, while the drive shaft rides on needle bearings.
- Repetitive Accuracy: Ensures consistent depth of cut with a tolerance of ±.001 in. (.025 mm) and countersink angles within ±1°.
- Interchangeable Tooling: Utilizes interchangeable countersinks and pilots.
- Optional Overtravel Feature: Available on #300 and #400 drives (ML-300-OT and ML-400-OT), this feature compensates for variations in part thickness and machine spindle overtravel up to .125 inch (3.17 mm), simplifying setups on automatic applications and multiple spindles.
- Operating Versatility: Suitable for use on virtually any type of shop equipment, hand-held power tools, or machine tools without requiring special operator skills.
