Operation

Installing Drills

Insert the drill into the chuck jaws with about 1" insertion. When using a small drill do not insert it so far that the jaws touch the flutes of the drill. Make sure that the drill is centered in the chuck before tightening the chuck with the key.

Positioning the Workpiece

Always place a piece of wood (or plywood) on the table. This will prevent "splintering" or making heavy burrs on the underside of the workpiece as the drill breaks through. The wood should contact the left side of the column.

pulling out the plug or switching off the main switch! Failure to comply may cause serious injury.

A coat of automobile-type wax applied to the table and column will help to keep the surfaces clean.

If the power cord is worn, cut, or damaged in any way, have it replaced immediately.

Lubrication

All of the ball bearings are packed with grease at the factory. They require no further lubrication.

Periodically lubricate the gear, rack, table elevation mechanism, the splines (grooves) in the spindle, and the teeth of the quill with a #2 tube grease.

Using the Vise

For the small workpiece that cannot be clamped to the table, use a drill press vise. The vise must be clamped or bolted to the table. Always use a back-up piece of scrap wood to cover the table. This protects both the table and the drill bit.

Basic Operation

Place material to be drilled in such as way as to come into contact with the left side of the column. This prevents the material from spinning.

If the work piece is not large enough to come into contact with the column, use a clamp or drill press vise that is securely fastened to the table! Failure to comply may cause serious injury!

Feed the bit into the material with only enough force to allow the drill bit to work. Feeding too slowly may cause burning of the workpiece. Feeding too quickly may cause the motor to stop and/or the drill bit to break.

Generally speaking, the smaller the drill bit, the greater the RPM required. Wood requires higher speeds than metal. Metal is usually drilled at slower speeds.

In dusty environments, frequently blow out any dust that accumulates inside the motor.

Maintenance

Before any intervention on the machine, disconnect it from the electrical supply by

115 Volt Operation

Referring to Figure 15:

As received from the factory, your drill press is ready to run at 115-volt operation. This drill press, when wired for 115 volt, is intended for use on a circuit that has an outlet and a plug that looks like the one illustrated in (A). A temporary adapter, which looks like the adapter shown in (B), may be used to connect this plug to a two- pole receptacle if a properly grounded outlet is not available. The temporary adapter should only be used until a properly grounded outlet can be installed by a qualified electrician. This adapter is not applicable in Canada. The green colored rigid ear, lug, or tab, extending from the adapter, must be connected to a permanent ground such as a properly grounded outlet box.

JDP-20MF specifications

The Jet Tools JDP-20MF is a powerful and versatile drill press designed to meet the needs of both professional woodworkers and DIY enthusiasts. Known for its impressive features, robust build, and advanced technology, this drill press provides users with precision and reliability for various woodworking tasks.

One of the standout features of the JDP-20MF is its heavy-duty 1 HP motor. This powerful motor ensures consistent performance, capable of handling a wide range of materials from softwoods to hardwoods with ease. With a variable speed control that ranges from 140 to 3000 RPM, users can easily adjust the speed according to the material and drilling requirements, ensuring optimal results for each application.

The JDP-20MF comes equipped with a 20-inch swing, which allows users to drill holes in larger workpieces without the need for repositioning. Its substantial table measures 12-1/2 inches by 24 inches, providing ample support and stability for large pieces. The table is also adjustable, tilting up to 30 degrees left and right, catering to a variety of drilling angles and tasks.

Another notable technology integrated into the JDP-20MF is the laser guide system. This feature projects a laser beam onto the workpiece, ensuring precise alignment and accurate drilling. This not only increases efficiency but also reduces the likelihood of costly mistakes, making it an invaluable tool for meticulous woodworkers.

Safety is paramount in the design of the JDP-20MF, as evidenced by its built-in safety key, which prevents accidental start-ups, and its sturdy metal housing that minimizes vibrations during operation. The drill press also features a work light to illuminate the drilling area, enhancing visibility and precision.

In summary, the Jet Tools JDP-20MF is a robust and feature-rich drill press that excels in both performance and versatility. With its powerful motor, variable speed settings, generous swing and table size, laser guide system, and focus on safety, it is an excellent choice for anyone looking to elevate their woodworking projects. Whether for a professional workshop or a home garage, the JDP-20MF stands out as a reliable and efficient drilling solution.
