Symptom
Possible Cause
Possible Solution
Tool falls out/loose
in spindle/chuck.
1. Tool loose or incorrectly installed.
2. Debris on tool or in spindle taper.
3. Excessive feed pressure.
1. Remove and re-install (
Page 24).
2. Clean tool and spindle taper, then re-install.
3. Decrease feed pressure and allow chips to clear.
Breaking tools or
cutters.
1. Spindle speed/feed rate too fast.
2. Taking too big of cut at one time.
3. Improper cutting technique or type of cut.
4. Cutting tool getting too hot.
5. Spindle extended too far down while
drilling.
1. Reduce spindle speed; reduce feed rate.
2. Decrease feed pressure and allow chips to clear.
3. Use right technique, tool, or machine for job.
4. Use coolant or oil for appropriate application (
Page
21); reduce cutting speed (Page 22).
5. Retract spindle and raise table to increase rigidity.
Workpiece or tool
vibrates or chatters
during operation.
1. Spindle extended too far down while
drilling.
2. Table locks not tight.
3. Workpiece not secure.
4. Spindle speed/feed rate too fast.
1. Retract spindle and raise table to increase rigidity.
2. Tighten table locks (
Page 25).
3. Properly clamp workpiece on table or in vise.
4. Reduce spindle speed (
Page 22); reduce feed rate.
Table hard to move.
1. Table locked.
2. Dirty or dry rack and pinion.
1. Disengage table locks (
Page 25).
2. Clean away chips/debris. Lubricate rack and pinion.
Spindle overheats.
1. Drill press operated too long at high
speeds.
1. Allow drill press to cool. Avoid operating at high
speeds for extended time.
Spindle does not
fully retract.
1. Poorly adjusted/worn return spring.
2. Debris on spindle/quill rack.
1. Replace/increase return spring tension (
Page 35).
2. Clean and lubricate spindle/quill rack.
Drill bit drifts.
1. Dull/incorrectly sharpened drill bit.
2. Tool/bit/chuck incorrectly installed.
1. Correctly sharpen drill bit.
2. Correctly install tool/bit/chuck.
Drill bit stuck in
workpiece.
1. Workpiece loose.
2. Lack of proper lubrication for workpiece
material.
3. Bit/cutting tool loose in chuck.
4. Spindle speed/feed rate too slow/fast.
1. Properly clamp workpiece.
2. Use appropriate lubrication for application (
Page
21).
3. Remove and re-install (
Page 24).
4. Adjust spindle speed (
Page 22); feed rate.
Workpiece thrown
from table.
1. Workpiece not secure; bit too large for feed
speed.
1. Properly clamp workpiece on table or in vise;
decrease feed speed.
Excessive runout or
wobbling in chuck/
drill bit.
1. Debris between chuck-to-spindle mating
surface.
2. Tool/bit bent or installed incorrectly.
3. Spindle bearings worn.
1. Remove chuck, clean, deburr tapered chuck and
spindle mating surfaces, reassemble.
2. Install tool/bit correctly or replace (
Page 25).
3. Replace spindle bearings.
Depth stop
inaccurate.
1. Depth stop not calibrated.
1. Calibrate depth stop (
Page 32).

workpiece splinters.
1. Scrap board not installed between table
and workpiece.
1. Install scrap board between table and workpiece.
Speed DRO display
is incorrect.
1. Speed sensor catching on pulley/at fault.
2. DRO circuit board wiring broken,
disconnected, or corroded.
