Cogsdill Micro-Limit Selection and Operation Guide

Cogsdill Micro-Limit Depth Controlled Precision Countersinking Tool

How it works…

The Micro-Limit is a precision depth-control countersinking tool. The tool consists of a drive with a piloted countersink and a depth control adjustment feature.

The tool is pre-set to the desired depth of cut. The selected setting is locked in for accurate and consistent results from part to part.

The pilot is engaged in the hole. A stop collar seats on the face of the workpiece; the tool advances to countersink the hole to the desired depth.

Design features

The Micro-Limit drive is designed and built for rugged production work. The thrust load is taken up on ball bearings through a hardened steel stop collar. The drive shaft rides on needle bearings. This design makes our drive the longest lasting in the industry.

Adjustment is in increments of .001 inch (.025mm).

Three drive models cover a wide range of hole sizes.

Countersinks & pilots

An array of interchangeable countersinks and pilots are available as standard.

Countersinks are offered with three standard angles. Special angles and carbide-tipped countersink are available upon request.

Pilots for hole sizes from .125 to .500 inch (3.17 to 12.7mm) are standard; intermediate sizes are available upon request.

Optional overtravel feature

Cogsdill Micro-Limt Tool With Overtravel

The MICRO-LIMIT is also offered with an overtravel unit built into the standard #300 and #400 drives. Ideally suited to automatic applications, the overtravel feature compensates for variations in part thickness and for overtravel of the machine spindle up to .125 inch (3.17mm).

The MICRO-LIMIT with overtravel also simplifies set-up for applications on multiple spindles.
