Kyocera OTM86183 Indexable Insert Drill 1 in 3xd

Product Description

The KYOCERA OTM86183 is a 1-inch diameter indexable insert drill from the Holeshot series, designed for high-productivity hole-making in metal cutting applications. Built on a steel body, it accepts two WCMX-style inserts and delivers a 3xD drill depth-to-diameter ratio, reaching a maximum drill depth of 3 inches. The right-hand cutting geometry and coolant-through capability make this drill a practical choice for shops running high-speed drilling cycles on machining centers or drill presses. Licensed machinists and tooling specialists are the primary installers and operators of this tooling system.

The OTM86183 is suited for production drilling in ferrous and non-ferrous materials where indexable insert tooling is preferred over solid carbide for cost-per-hole efficiency. The Whistle Notch shank provides a positive drive connection in compatible tool holders. With a body length of 3.9 inches and a shank length of 2.28 inches, this drill fits standard machine spindles that accept a 1-inch Whistle Notch interface. It is a single-unit package with a minimum order quantity of one.

Key Features

• 1-inch cutting diameter with 3xD depth-to-diameter ratio for a maximum drill depth of 3 inches
• Accepts two WCMX 050308-M1A indexable inserts for quick edge changes without removing the body
• Coolant-through design directs coolant directly to the cutting zone for improved chip evacuation and tool life
• Whistle Notch shank provides positive rotational drive and accurate radial location in compatible holders
• Right-hand cutting direction compatible with standard spindle rotation on CNC machining centers and drill presses
• Steel body construction balances rigidity and weight at 1.2 pounds

Compatibility

Designed for use with WCMX 050308-M1A indexable inserts. The 1-inch Whistle Notch shank is compatible with tool holders conforming to that interface standard. Confirm spindle clearance and holder compatibility before installation.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling technician familiar with indexable drilling systems. Ensure the machine spindle is fully stopped and locked out before mounting or dismounting the drill body or changing inserts. Verify that insert seating surfaces are clean and free of chips before torquing insert screws to the insert manufacturer specification. Confirm coolant-through passages are open and coolant pressure is set per the machine tool requirements before beginning a drilling cycle.
