STANDARD DRILL BIT CARE

Check for Drill Spindle Wobble

Spindles could be badly worn or even bent through miss-adjustment, have them replaced immediately. A wobbly or loosely held drill bit will break.

Keep Drill Spindle Clean

Remember to clean out the drill spindle frequently. This will prevent any buildup in the spindle of the drill.

Keep Drills Bits Clean

A dirty and rusty drill will not permit the free upward passage of the drill chips. Pressure built up by a clogged drill will split or break the drill. To keep it free from dirt or rust, clean the drill of all chips after each use and apply light oil to the inside and outside. Drills should be cleaned out immediately after each use. This is particularly true if a coated or varnished stock has been drilled. When drilling laminates or plastics you should drill a few lifts of plain paper before shutting down machine, this will clear out the plastic before the bit cools down. On these jobs the coating on the chips frequently fuse the chips into one solid mass when the drill cools, making it hard to clean or causing breakage the next time the drill is used

Keep Drill Bits Sharp

Dull drill bits is the major cause of drill breakage and production tie-ups. Normally, after only three hours of drilling (depending on the type of paper being processed) the drill bits should be sharpened. A dull drill bit results in poor quality work, and the need to buy new bits more often.

Lubricate Drills

Lubrication assists in the passage of the chips and helps avoid overheating of the drills. Use readily available stick lubricants for this purpose. Hold the end of the stick against the side of the rotating drill. CARE MUST ALWAYS BE TAKEN WHEN HANDLING OR LUBRICATING DRILLS.

Make Sure to Set the Depth of the Drill Bits Correctly

Do not cut too deeply into the cutting block. The drill should just touch the block and cleanly cut through the bottom sheet. During drilling, do not set the drill deeper into the block instead change the position of the block frequently. Drilling deeper into the block dulls the drills quickly. Use a piece of chipboard underneath your stock. This will make handling the stock easier and will ensure that the last sheet is cut cleanly through.

Inspect Your Drill Sharpener Carbide Reamer

The cutting edge of the Carbide Reamer should be inspected frequently to make certain that it is sharp and free of nicks. Never let a drill bit drop onto the Carbide Reamer. It will chip the sharpening edge. Use gentle pressure when sharpening - let the Carbide Reamer do the work. Check the sharpness of the drill after sharpening. The cutting edge should be razor sharp.

Always refer to your OEMs owner’s manual, for the safe operation of your equipment. To prevent the drill from overheating, always avoid drilling too slowly. The SHARP drill bit should pass though the paper as rapidly as possible while also allowing the drills to easily cut through the paper. Care should be taken when handling hollow paper drill bits, they can be very sharp and dangerous. Avoid touching sharp edges.
