 ==Drill==
 Drills use [[drill bits]] to remove material and create a hole. Other attachments can be installed such as: burs, sanders, grinders, and polishing wheels.

 ===Laser Cutting===
 ===Water Jetting===
-Water Jet cutting<span>is performed by a high pressure jet of water containing an abrasive grit.</span>Therefore, it is usually higher quality than laser or plasma because it doesn't use heat and won't warp the part. The workpiece can also be non-metallic such as carbon fiber or plastic. Water Jet can hold good ~±0.1mm (~±0.005") tolerances depending on the machine used. Before welding a water jet part, the surface needs to be prepared more than usual to remove abrasive imbedded in the surface. Quotes for water jet jobs are very budget friendly and have a faster turn around time than conventional machining.

This process is often called "burning". EDM only works with metallic parts and will not work with most coatings. With the right operator and enough passes, EDM can hold very tight tolerances <±0.025mm (<±0.001).

 ===Drill Press===
 Drill presses are more stable than hand drills. They have a movable table to attach a [[Machining#presses#vice|vice]] and a spindle with a chuck. The RPM is typically controlled by a gearbox and sometimes with a VFD; feed rate is controlled by pressure applied to the spindle lever. Walking the drill bit is less likely, but a center punch is still recommended.
