9) REMEDIES FOR HOLE MAKING PROBLEMS 

 

Problem 

Cause 

Remedy 

1) Magnetic base 

won’t hold 

effectively 

Material being cut may be too thin for efficient 
holding. 
 
Swarf or dirt under magnet. 
 
Irregularity on magnet contact or workpiece. 
 
Insufficient current going to magnet during drilling 
cycles. 

Attach an additional piece of metal under the 
magnet, or mechanically clamp magnetic base to 
workpiece. 
 
Clean magnet. 
 
Use extreme care; file any imperfections flush to 
surface. 
 
Confirm power supply and output from control unit, 
check supply cable. 

2) Cutter skips 
out of centre-
punch mark at 
initiation of cut 

Magnetic base is not holding effectively. 
 
Worn arbor bushing and/or ejector collar. 
 
Too much feed pressure at start of cut. 
 
 
Cutter is dull, worn, chipped or incorrectly 
sharpened. 
 
Poor centre-punch mark; weak pilot spring; pilot not 
centred in centre-punch mark. 
 
Worn or bent pilot, worn pilot hole. 
 
 

See causes and remedies above. 
 
New arbor bushing is needed. 
 
Light pressure only is needed until a groove is cut.  
The groove then serves as a stabilizer. 
 
Replace or re-sharpen. Sharpening service is 
available. 
 
 
Improve centre-punch and/or replace worn parts 
 
 
Replace part or parts 
 

3) Excessive             
drilling pressure 
required 

Incorrectly re-sharpened, worn or chipped cutter. 
 
Coming down on swarf lying on surface of 
workpiece. 
 
Swarf accumulated (packed) inside cutter. 
 

 Re-sharpen or replace. 
 
Take care not to start a cut on swarf. 
 
 
Clear cutter. 

4) Excessive 
cutter breakage 

Steel swarf or dirt under cutter. 
 
Incorrectly re-sharpened or worn cutter. 
 
 
Cutter skipping. 
 
 
Cutter not attached tightly to arbor. 
 
Insufficient use of cutting oil or unsuitable type of 
oil. 
 
 
 
 
Incorrect speed 

Remove cutter, clean part thoroughly and replace. 
 
Always have a new cutter on hand to refer to for 
correct tooth geometry, together with instruction 
sheet. 
 
See causes and remedies (2). 
 
Retighten. 
 
Inject oil of light viscosity into the coolant-inducing 
ring and check that oil is being metered into cutter 
when pilot is depressed.  If not, check pilot groove 
and arbor internally for dirt or apply oil externally.  
(Even a small amount of oil is very effective).  
 
Ensure correct speed is use for the cutter. 
 

5) Excessive 
cutter wear 

See cause and remedy above 
 
Incorrectly re-sharpened cutter. 
 
 
Insufficient or spasmodic cutting pressure. 

 
 
Refer to instructions and a new cutter for proper 
tooth geometry. 
 
Use sufficient steady pressure to slow the drill down.  
This will result in optimum cutting speed and chip 
load.
