INSTRUCTIONS FOR USE AND CARE OF CARBIDE-TIPPED ROTARY MASONRY DRILLS
1. USE IT WITH - rotary electric portable drills, drill presses or
hand braces. Do not use in hammer-type percussion drills.
2. SPEED - For best results use heavy-duty, slow speed electric
drills with 400 to 750 RPM. For extremely hard materials,
slower speeds, from 100 to 200 RPM, will give better results.
3. PRESSURE - For best results use sufficient pressure to keep
drill cutting at all times.
4. LUBRICATION - Although dry drilling produces excellent
results, a lubricant sometimes helps on very hard materials

such as glazed tile, porcelain, marble, etc. Turpentine,
kerosene or water may be used as lubricants, and enough
should be applied to keep the entire drill point wet.
5. HOW TO SHARPEN - These drills can be sharpened on any
tool grinder, although silicon wheels are recommended.
When sharpening, use moderate pressure, and keep drill
continually moving across the wheel. Use the same angles
as for steel drills, and keep the drill dry at all times during
sharpening.
