The drill press cuts holes of different sizes in different materials. It can be used to drill wood, plastics, ceramics, or metals. What matters when drilling the different materials is the type of drill bit chosen.
To make cross cuts, miter cuts, bevel cuts, and compound cuts using a sliding miter saw.

* Safety glasses to be worn when drilling
* Always wear approved safety glasses or face shield while operating the equipment.
* Proper clamping and holding (fixtures and jigs) the wood when drilling
* Before operating equipment, remove tie, rings, watches and other jewelry, and roll sleeves up past the elbows. Remove all loose clothing and confine long hair.
* Proper speed selection for size of bit and material to be drilled
* Non-slip footwear or anti-skid floor strips are recommended.
* Remove chuck key prior to drilling
* Closed toe shoes are required when working in a shop area.
* Assure bit is centered in the chuck – no wobble
* Do not wear gloves while operating the equipment.
* Remove all loose clothing, jewelry, and confine long hair.
* Make all machine adjustments or maintenance with the machine unplugged from the power source.
* Do not wear gloves.
* Do not attempt to saw boards with loose knots or with nails or other foreign material, on its surface.
* Assure that the bit is sharp and no imperfections
* Always keep hands and fingers away from the blade.
* Do not force tool when cutting.
* Secure work piece with clamping.
* Never use the slide compound miter saw with its lower guard locked in the open position.
* Ensure that the lower guard moves smoothly.
* Do not use the saw without guards in position.
* Use correctly sharpened saw blades.
* Observe the maximum speed marked on the saw blade.
* Do not use saw blades that are damaged or deformed.
* Never attempt to saw stock that does not have a flat surface, unless a suitable support is used.
* Always allow the saw blade to stop before removing scrap pieces from the table.
* Do not remove jammed pieces from the saw until the machine and blade has stopped. Unplug the band saw from the power source, and then remove the jammed work piece.
* Always turn off the machine if the material is to be backed out of an uncompleted cut.
* Remove material or debris from the work area. Keep work area neat and clean.

* Assure the bit is centered in the chuck, spin chuck to verify
* Check blade is square to table and back fencing
* Use correct spindle speed – see [https://vector-space.org/sites/default/files/drill_cheat_sheet.jpg chart] attached to the drill housing
* Start saw with the blade fully in the up position to control torque
** Smaller bit – higher speeds
* Cuts are to be made when blade is a full speed
** Larger bit – lower speeds
* Stopping the cut/blade – leave in down position until blade is completely stopped
** Softer materials - higher speeds
* Use stop blocks for repetitive length cuts
** Harder materials - lower speeds
* Saw blades need to be 291 mm to 305 mm external diameter.
* Place scrap wood beneath your part to avoid drilling into the table
* Start cutting only after motor revolution reaches maximum speed.
* For deep holes, may need to peck drill to remove chips from hole
* During a miter or bevel cut the blade is not to be lifted until it has stopped rotation completely.
* Don't lose the chuck key
* For slide cutting operation, the saw must be pushed and slid away from the operator.
* Put bits away– don't leave them in the chuck (easy to forget)
* Use clamping when drilling small parts

 TBD
 
== '''Excessive Vibration''' ==
 
Causes
 
* When the spindle or table handles go faulty, the drill press is likely to have excessive vibration.
* High power voltage can also be responsible for excessive vibration of the drill press.
 
Solutions
 
* Make sure the drill press works at a power rate that is very stable at all times. A power stabilizer can be best to secure this.
* Make sure the spindle handles are well and in place all the time, in use and out of use.
 
== '''Bits Wandering''' ==
 
 
 
 
 
Causes
 
* Bits wandering is caused mainly by excessive feed rate. When bits fed into the material gets too much, the bits begin to wander.
* Chuck jaws holding the bits not being in place or firmly secured can bring about bits wandering.
 
Solutions
 
* Make sure that bits being fed into material are not too much. Feed materials with the required number of bits per time.
* Also make sure that the chuck jaws are firm and properly tightened to keep the bits in its place.
 
== '''Noisy Operations''' ==
 
Causes
 
* The spindle getting dry can cause the drill press to begin making noise excessively thereby producing really loud noise.
* Loosed pulleys have ask been major causes of excessive noise witnessed by a number of drill press users.
 
Solutions
 
* Constantly grease the spindle to avoid it from going dry on a timely basis depending on how often and how long the drill press is used.
 
== '''Wood Splinters Underside (chip-out)''' ==
 
Causes
 
* The singular cause of this is when the work piece lacks the support needed in terms of back up material to keep it firm.
 
Solutions
 
* [https://www.sciencedaily.com/releases/2014/05/140507095851.htm Make use of scrap woods] or pieces under the current workpiece to give it all the support it needs.
 
== '''Wobbling Drill Bits''' ==
 
Causes
 
* Wrong or incorrect installation has been the major reason why bits wobble. For bits to function well, they have to be properly installed well in the chuck.
* Incorrect sharpening of the bits before putting them in their place also contribute to wobbling drill bits.
* A bent bit or a totally damaged shank can also cause the bit to wobble while being used.
 
Solutions


* Make sure to check the bits installation and be sure it is adequate. Any inconsistency noted in the installation should be rectified immediately
* Bits should also be well sharpened before placing them in the chuck where they should be.
* For damaged bits and shank, nothing except a replacement can be done to them. Replace damaged shank immediately to avoid further damage to the drill press.


 
== '''Binding or Slipping Work Piece''' ==
Causes
* Unsecured bits or improper installation of them is what is responsible for binding or slipping work piece.
Solutions
* To solve this, all you need to do is to install the bits properly and ensure they are well secured in its place.
== '''Loosening Work Piece''' ==
Causes
* For the work piece to be firm, it has to be supported by a clamp that fixes it to the table. When this clamp or support is absent, work pieces begin to loosen.
Solutions
* Make sure the work piece is well fastened to the table and supported with the clamps made available.
