Motor and belt speed
With power disconnected, belt placement selects spindle speed from the model's chart. Close the cover before restarting; choose speed for bit diameter and wood rather than treating one speed as universal.

02 / Understand the tool
What it is and what each part does
A drill press brings a rotating bit down through a fixed vertical path into clamped stock. The JET JDP-17 reference is a floor machine with a belt-and-pulley speed system, a depth stop, a rack-raised table and a 5/8-inch chuck. A handheld drill reaches assembled work, but depends more on the operator or a jig for angle and repeated depth. A press is limited by its throat, quill travel and table clearance.
An induction motor drives the spindle by belt and pulleys inside the closed upper cover. Feed handles lower the quill and spindle; a return spring brings them back. The chuck and arbor hold the bit. The table, column and base provide a rigid reference. The poster separates documented groups to teach function, not a service or assembly sequence.
Quill, spindle and chuck
The quill moves vertically while the spindle rotates inside it. The taper-held arbor and keyed chuck grip a suitable bit; remove the chuck key before power is restored.
Feed and depth stop
Feed handles control descent; the depth stop limits a repeated stroke. Confirm the stop against scrap, especially with a pointed bit or a sacrificial backer.
Table and rack
The table raises on the column rack, rotates and tilts for work access. Lock all adjustments and verify squareness before a precision hole.
Column and base
The cast base supports the column and machine head. Secure the press and keep its center of mass stable; long stock needs separate support.
Switch and return
Know the stop switch location and check that the quill returns without binding. Faulty return, chuck retention or unusual vibration calls for service.

These decisions make the mechanism useful at the bench.
Choose speed
Read the JDP-17 speed chart, bit instructions and wood condition. Disconnect power before moving belts; tension and close the pulley cover as directed.
Lock the work
Clamp the blank or use a drill-press vise anchored to the table. Round, narrow or small pieces can spin violently if held by hand.
Set depth
Mark the center, select a bit, set a backer and dry-run the stroke. Use the depth stop for repeat holes and clear chips during deep cuts.
Hardware holes
A fence, stop block and clamped stock place repeated shelf-pin, handle or hinge holes consistently.
Flat-bottom recesses
A properly sized Forstner bit makes controlled recesses; use light feed and clear chips before heat builds.
Joinery preparation
Use a fence or jig to keep a row of dowel or mortise-waste holes aligned, then finish fit with the appropriate tool.
03 / At the bench
Setup, technique and finish quality
Use the steps for a first pass, then inspect the work before changing the setup.
- Read the JDP-17 manual, check bit size and choose a suitable spindle speed.
- Disconnect power; inspect the chuck, belt, table lock, feed return and cord.
- Set the table square or to the intended angle; place a sacrificial backer under through-holes.
- Clamp the work and fence or vise to the table; check clearance throughout the feed stroke.
- Seat the bit, remove the chuck key, set depth and close the belt cover.
- Start clear of stock; feed steadily, withdraw as needed to clear chips and avoid excessive force.
- Switch off, wait for full stop, then unclamp and inspect the hole before repeating.
Center and registration
A brad-point spur helps a hole start at a mark. A fence and stop can make location more repeatable than aiming at each mark alone.
Bit and speed
Larger bits often need lower speed and greater chip clearance. Follow the bit maker and JET chart instead of extrapolating from small twist bits.
Exit quality
A backer supports the wood fibers at breakthrough. Verify its placement and clamp it with the work.
Taper and chuck
A slipping or wobbling chuck may indicate a dirty or improperly seated taper. Follow the model manual's correction, never grip a turning chuck.
What changes by model or material
Floor presses offer more table-to-chuck clearance; benchtop machines trade capacity for footprint.
JDP-17 uses a belt arrangement. Other machines change speed by mechanical or electronic controls; the speed and service instructions differ.
Swing limits how far a hole can be from a board edge. Quill travel limits uninterrupted depth; neither alone describes usable clearance.
Chuck capacity and spindle taper are separate specifications. Match the bit shank to the chuck and use only approved tooling.
Choosing the tool
- Compare swing, spindle travel and table-to-chuck clearance with your actual stock.
- Check table locking, speed range, stable base and available chuck/bit sizes.
- Budget for secure workholding and a suitable dust or chip cleanup method.
Useful accessories
- Clamped drill-press vise or fence and stop.
- Sacrificial backer and long-stock support.
- Depth setup gauge and task-appropriate clamps.
Consumables
- Sharp brad-point, twist or Forstner bits suited to wood.
- Replaceable backing boards.
- Model-specified belts or chuck parts when worn.
04 / Keep control
Care, troubleshooting and safety
Stop the tool and disconnect power before investigating a fault or changing a part.
Care checklist
- Disconnect power before belt or bit changes.
- Keep the table, taper and quill area clean; follow manual lubrication points only.
- Inspect belt condition, table lock and quill return.
- Check chuck security and bit runout if vibration changes.
Common mistakes
- Holding small work by hand.
- Leaving the chuck key installed.
- Running a large bit too fast or feeding a dull bit harder.
- Using the depth scale without a scrap check.
Safety at the operation
- Clamp stock and keep hands clear of rotating bits and chuck.
- Tie back hair; avoid gloves and loose sleeves near rotation.
- Wear eye protection and manage chips without reaching toward a moving bit.
- Stop and disconnect power before adjusting belts, table or chuck.
When the result goes wrong
Check bit sharpness, center mark, table/fence registration, work clamping and feed pressure.
Check speed, bit condition, chip clearance, belt tension and clamping; stop if vibration persists.
Check stop lock, table lock and backer compression; confirm on scrap.
