Specifications

Included Sizes and Decimal Diameters

One drill in each size. All decimal diameters are in inches.

Tool Compatibility and Use

Use a pin vise, precision drill chuck, or suitable collet capable of gripping the selected drill diameter. Check your tool’s minimum gripping capacity; standard drill chucks may not close sufficiently to hold these small shanks.

Secure the workpiece, maintain accurate alignment, and apply light feed pressure. Avoid side loading and clear chips frequently. Select drilling speed and lubrication to suit the material and drill diameter.

Check the size range before ordering: All drills in this set are smaller than 1/16″. Higher wire gauge numbers indicate smaller diameters within this range.
