- Remember to
re-tighten the table lock lever before using the drill
- Always check
the drill press speed chart to determine correct combination of material,
bit size, and drilling speed
- Insert drill
bits about 3/4" (and at least 1/4") into the chuck and tighten
securely with the chuck key
- The chart is
located on the wall behind the drill press
- Factors which
determine the best speed:
- Kind of material
being worked (metal, acrylic, aluminum, wood, etc.)
- Size of hole
- Type of drill
bit (see pictures below)
- Quality of
cut desired
- Typically, the
smaller the drill bit, the greater the required RPM
- In soft materials,
the speed should be higher than for hard materials
- To drill a through
hole without splintering the bottom face, place the material on a
scrap piece of wood. This also protects the point of the drill bit
- !!!IMPORTANT!!!
Use a scrap piece of wood to also prevent drilling into the metal
table surface
- Setting the depth
stop can also avoid this problem. Drilling into the table not only
damages the table, but also the drill bits
- To prevent rotation
of the work piece, clamp the work secure to the table, either with
a "C" clamp or the drill press clamp
- When using paddle/spade
drill bits, you should always use a hold down clamp
- Paddle bits are
not to be used on metal
- When drilling
into metal, a cutting lubricant should be used. Cast iron and brass/bronze
should be drilled dry
- Return bits to
drawer when you are done and clean the area around the press
