Kyocera OTM86155 Indexable Insert Drill 5/8in 3xd

Product Description

The KYOCERA OTM86155 is an indexable insert drill from the Holeshot series, designed for precision hole-making in metal cutting applications. It accepts two WCMX-style inserts and drills to a maximum depth of 1.87 inches at a drill-to-diameter ratio of 3xD. The body is constructed from steel and features a 5/8-inch cutting diameter with a 3/4-inch whistle notch shank for positive drive in compatible tool holders. Coolant-through capability helps manage chip evacuation and heat at the cutting zone. This drill is suited for machinists, toolroom technicians, and production CNC operators.

The OTM86155 is intended for use in CNC machining centers and manual mills where indexable insert drills are specified for production or prototype drilling operations. The 3xD depth ratio makes it well suited for shallow-to-moderate depth holes in ferrous and non-ferrous materials. The whistle notch shank design requires a compatible drill chuck or tool holder with a drive flat to seat correctly. The 2-insert configuration places one insert at center and one at the periphery for balanced cutting forces across the full drill diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with indexable tooling. Ensure the machine spindle is fully stopped and the tool holder is properly torqued before mounting this drill body. Verify that the tool holder accepts a 3/4-inch whistle notch shank and that internal coolant lines are clear before enabling through-spindle coolant. Inspect insert seating pockets and securing screws before each use; a loose insert can cause tool damage or workpiece failure.
