Drill Press Operations
Symptom Possible Cause Possible Solution
Breaking tools or cutters. 1. Spindle speed/feed rate is too fast.
2. Cutting tool getting too hot.
3. Spindle extended too far down.
1. Set spindle speed correctly (Page 25) or use a
slower feed rate.
2. Use coolant or oil for appropriate application.
3. Fully retract spindle and lower headstock. This
increases rigidity.
Drilling stops, but the motor
still operates.
1. Bit slips in chuck. 1. Tighten bit; inspect bit for burrs or other obstructions
that might interfere with clamping surface.
The chuck wobbles or is
loose on the spindle shaft.
1. Foreign material is stuck between
the arbor-to-spindle mating surface.
2. Damaged chuck or arbor.
1. Remove the arbor/chuck assembly and clean the
tapered arbor and spindle mating surfaces, then
reassemble.
2. Replace as necessary.
The spindle does not retract
completely in the uppermost
position or it binds.
1. The quill shaft is gummy with metal
chips and oil.
1. Clean shaft and lubricate with a light coat of oil.
The quill has excessive
deflection.
1. The quill bearings are worn or
damaged.
2. The quill shaft is at fault.
1. Replace the bearings.
2. Replace the quill shaft.
Drill bit wobbles, holes are
oversized.
1. Drill bit installed incorrectly. 1. Remove drill bit and re-install.
Workpiece vibrates or
chatters during operation.
1. Table locks not tight.
2. Workpiece not securely clamped to
table or into drill vice.
3. Spindle speed/feed rate is too fast.
4. Spindle extended too far down.
1. Tighten table release handles (Page 24).
2. Check that clamping is tight and sufficient for the job.
Make sure drill vice is tight to the table.
3. Set spindle speed correctly (Page 25) or use a
slower feed rate.
4. Fully retract spindle and raise table. This increases
rigidity.
