- Use of water is not necessary, but can reduce or eliminate dust and keep bit cooler; however, it must be applied from start of drilling and not after bit has heated, as this will shock carbide insert. Use of water around electricity can be deadly. Take all necessary precautions to prevent shock.
- Leaning on a bit that is not drilling straight in effort to straighten it is not recommended. This can cause bit to break and user to fall and cause injury.
- Always wear appropriate protective gear: safety glasses, dust mask, hearing protection, gloves, boots, etc.
- Always drill with adequate lighting and ventilation and from a solid standing position.
- Always drill with the shortest bit possible.
- Never drill deeper than the flutes (unless the flutes are larger in diameter than the bit body) and keep flutes clear of debris. Failure to clear flutes may cause binding and/or breaking of bit.
- Always maintain drill motor according to manufacturer's owner manual.
- Read all related instructions, owner manuals, etc. before use of any tool.
- Use properly rated extension cords with no damage to insulation.
- Consult manufacturer if you have any questions or concerns.
- Do not use drills as pry bars or for any application other than their designed use.
- Do not attempt to hammer drill through reinforcing steel (rebar). This will damage the hammer bit. Use a Relton rotary rebar cutter.
- Consult with structural engineers if you have any concerns before cutting rebar.
- All Relton carbide tools (bits and hole saws) can be resharpened or re-tipped.
- Keep carbide tipped masonry bits sharp to reduce heat and increase drilling speeds.
- Use of a depth guide avoids over drilling and excessive use of chemical epoxy anchor, which will save time, money, and prolong the life of the bit.
- If setting anchors, use the bit diameter recommended by the anchor manufacturer.
- Never operate drills or related equipment during or after consuming alcohol or drugs.
- If using a RELTON product, SMILE! – You're using the BEST! Made in USA since 1946.
