Jet 350017 Mill Drill R-8 Taper 1HP 115/230V

Product Description

The JET 350017 is a mill drill machine built for precision metalworking and machining operations in professional shop environments. It accepts an R-8 taper spindle, the standard found in most bench and floor mill drills, making tooling changes straightforward with commonly available collets and end mill holders. Rated at 1 horsepower on a single-phase motor, it runs on either 115 or 230 volt power, giving the installer flexibility to match the available circuit in the shop. At 457 pounds, this is a floor-standing or heavy bench unit that requires proper anchoring before use. Machinists, tool and die workers, and general fabrication shops are the primary users of this class of machine.

The JET 350017 suits light to medium-duty milling and drilling tasks in job shops, maintenance facilities, vocational training environments, and small-scale production settings. The R-8 taper spindle is widely used in American mill drill machines, and the dual-voltage motor makes installation practical in both residential shop and commercial facility electrical configurations. This machine is not intended for CNC conversion without additional engineering review.

Key Features

• R-8 taper spindle accepts standard collets and tooling common to mill drill machines
• 1 HP single-phase motor rated for 115 or 230 volt operation
• Dual-voltage capability allows flexibility for available shop circuitry
• Substantial 457-pound construction provides rigidity and reduces vibration during cutting operations
• Sold as a single unit (each)

Compatibility

Designed as an OEM-style replacement or direct unit purchase for shop environments requiring a mill drill machine with an R-8 taper spindle and single-phase power.

Installation Notes

Installation should be performed by a qualified electrician for final wiring, following NEC requirements for the selected voltage configuration (115 or 230 volt). Confirm the available circuit ampacity before connecting. The machine must be securely anchored to the floor or a suitable stand rated for the 457-pound load before operation. Disconnect and lock out power completely before performing any tooling changes or spindle adjustments.
