Onsrud 91-136 T20 Torx Plus Indexable Driver

Product Description

The ONSRUD 91-136 is a T20 Torx Plus drive driver designed for use with indexable spoilboard surfacing cutters. It provides the correct drive interface for seating and removing indexable insert screws on compatible ONSRUD tooling. Weighing 0.17 pounds, this compact driver is built for bench and floor use in CNC router shops and woodworking production environments. Technicians and machinists rely on a properly matched driver to prevent cam-out and protect the seating torque of indexable insert hardware.

This driver is intended for use during insert changes on indexable spoilboard surfacing cutters. It is compatible with insert screw part number 91-133 and complete insert assemblies 91-125 and 91-127. Spoilboard surfacing operations are common in CNC flatbed routing, where inserts are changed frequently. Having the correct T20 Torx Plus driver on hand reduces downtime during insert rotation and replacement.

Installation Notes

Insert changes on indexable tooling should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the spindle before removing or seating inserts. Use only the specified Torx Plus driver to avoid rounding the screw drive and compromising insert clamp force. Follow the tooling manufacturer's recommended insert seating procedure to ensure secure clamping before resuming cutting operations.
