- Pillar Drill
- Workshop Category: W3
- Workshop Risk Category: Yellow Label
Suitable only for Perspex/acrylic, wood, some metals, according to type of drill bit (e.g. H.S.S., Tungsten
Carbide). If in doubt ask.
The pillar drill has a motor driven head that has a chuck that accepts bits or cutters. It also has an adjustable table on which the work is mounted. It is operated by pulling a rotary lever which lowers the drill bit into the material. To avoid accidents, the following operational safety rules must be observed by everyone working on the pillar drill.
Start with a Risk Assessment to ensure a safe work area:
- The area around the drill press must be kept clear of people, debris and sawdust.
- Safety glasses or a face shield must be worn. Hearing protection should be worn.
- Remove loose fitting clothing, jewellery, and tie back long hair.
- Give the work your undivided attention.
- Do not wear gloves or anything that would allow a hand, fingers or clothing to be wrapped around the revolving bit.
Operational Safety Rules:
- Approach your work in the workshop and on the drill press with a safe attitude.
- Make all drill press adjustments with the power shut off.
- Keep all guards and covers on the machine when it is on and running.
- Make sure the size of the bit is equal to or less than the capacity of the drill press.
- Use the recommended speed for the material you are drilling (the harder the material the slower thespeed).
- It is good practice to centre punch the drill-hole location into the stock.
- Insert bit into drill chuck and tighten.
- Use a clamp or vice to securely fasten the stock to the drill press table. Never attempt to handhold stock while drilling.
- Drill into cylindrical stock using a “V” block.
- Long stock should be drilled with the excess to the left of the operator. So if the stock rotates it will hit the post, not the operator.
- Support the underside of the stock to be drilled with a backer board secured to the drill press table.
- Never start the machine without the table clear of everything except the stock you are drilling.
- Keep hands and fingers at least 8cm from rotating drill bits.
- When drilling deep holes, frequently raise the drill bit from the hole to remove cuttings and cool the bit.
- When you begin to break through the underneath side of the stock, ease up on the pressure as to not tear the wood from the underneath side.
- If a drill bit binds, turn off the drill press and carefully turn the drill chuck backwards by hand to free the drill bit.
- Never reach around or under a rotating drill bit or grab the chuck to stop a drill press. This can result in hand puncture or other serious injury.
- Turn the drill press off before looking up or walking away from the machine.
- Never stop the rotation of the drill chuck, spindle, or stock rotating on the bit with your hands or fingers.
- Don’t touch the drill bit and shavings since they are hot immediately after drilling. Wait until they have cooled down.
- Always clean the drill press table and work area upon completion of the drilling task. Do not use your hands or blow the drill shavings, use a bench brush.
