K2 DIAMOND Performance Tips

Core Bits like to run fast
Multi-segment bits work better at higher RPM than surface set bits. This is especially true at smaller sizes. So be sure to keep your RPMs up.
Don't apply to much pressure
Let the diamonds and the speed of the bit do the work. For example, using a cheater bar to apply additional pressure tends to dull the smaller sized diamonds.
Give your bit some horse power!
Don't try to "get away with" using a less powerful, lighter weight electric drill, except on small bits.
Diamond core bits can be sharpened
If you think your bit has begun to run dull, simply run your blade on some soft, abrasive brick or block. This will help expose and sharpen new diamonds so that it will cut like new.
Don't bounce your bit when cutting tough materials
Multi-segment bits are designed to cut best with an even medium pressure. Don't "bounce" the bit to get a bit into the material, just continue applying even pressure.
Please don't hit your bit with a hammer. This will only get your bit out of shape and reduce its overall performance.
Segments can be replaced
If you lose a segment here or there or damage one, we can replace them. Call us for a quote on repair services .
Select the proper hardiness & grade for your application
Core bit segments are available in several different hardnesses and bonds to meet your application needs. For example, we can adjust the bond for hard rocks, heavily reinforced concrete and other job factors that you may come across.
Run your blade at the recommended speed
Blades should generally be run at about 9,000 surface feet per minute. This means that larger blades should be run at lower RPMs than smaller blades. If you want to help sharpen a dull blade, try running it for a short time at a reduced RPM. If the blade seems to be wearing too rapidly, try running it at a faster speed.
Use Plenty of water on wet blades
A good water flow on both side of the blade of about 4 to 5 gallons per minute (not high pressure) is best. Hydrant pressure is more than required.
Tighten your blades properly
The the blade is snugged up with clean and even sized flanges, which are free or of burrs and rust it will run straighter and truer for maximum efficiency. Bad seating results in lopsided were, egg shaped or burnt arbor holes.
Always use the right blade for the job
Green Concrete, old concrete, bricks and clay, asphalt, wall sawing etc, all have their own unique characteristics. Making sure your blade is suited to your cutting job will result in faster, easier cutting and better blade life.
Always use the correct power
The more horsepower (torque, not pressure on the blade) supplies to the spindle, the more efficient the cutting action will be. Low horsepower may require a softer blade.
Use plenty of water to flush out the slurry
The cuttings if not properly flushed out of the cut will compromise both the matrix and the steel core resulting in shorter blade life. Be sure to maintain sufficient water flow for proper slurry removal.
Always use the correct diameter and width of the blade for the job
Blades come in various widths and diameters in order meet your job requirements. If you have any questions, call us anytime for our recommendation at 1-800-539-6116.
Make sure your blades run round
Check your machine for bad bearings of bent or worn shafts. These cause the blades to run out of round and create excessive wear and stress. Good machine maintenance will give longer blade life and easier cutting.
Don't use to much cutting pressure
Excessive pressure on the blade will dull the diamonds, create stress on the steel core and cause the blade to become out of round. On lighter saws, to much pressure causes the blade to rise out of the cut and will lug the motor down. If you hear a smooth motor sound, you know your blade is running properly. If you hear a decrease in RPMs as your are cutting, you may have a problem with your blade or you are exerting too much pressure.
Always use the correct blade direction
Blades are designed to cut in one direction, as shown by the arrow on the blade. Always make sure you blade is attached to your machine such that it spins in the correct direction. Longer blade life and better cutting will result.
Keep your blade out of sand
If you cut through the asphalt or concrete slab into the sub-base, water loss will occur and the abrasion of the sand will put extreme wear on both the steel core and the diamond segments.
