Tech offers the largest selection of jointing stones in the world!
After many years of product testing, we have endorsed a select group of
products, including the well-known Atlantic products. These stones are
accepted world-wide as the "cream of the crop", and are made
of high-purity silicon carbide. The result is a longer stone life, superior
finish, and absence of impurities in the product.
types of jointer stones (Hard and Soft) are used in the woodworking industry.
In general, hard stones are used on older machines running at 3,600
RPM's. Detail to precisely forming the stone is critical, as the stone
can "reform" the profile on the knife if mis-made. Soft stones
- as used on more modern 6,000 and higher RPM machines, are more forgiving
and can be "chipped in" to properly fit the knife.

HELPFUL HINTS :
Note: Grinding accuracy is critical in determining proper jointing stone selection.
First, layout the stone using the pattern knife to be jointed. It is most important to maintain as accurate a mirror image fit as possible to the profile being jointed, as the jointing stone will in effect re-profile the knife if not properly formed. Now pre-shape the stone as accurate a fit as is possible.
Taper the stone on both sides at a 45° angle. This angle allows faster chipping-in of the stone. Insert the stone into the holder on the machine, and chip the stone in for exact fit. The use of only one knife in the chipping-in process results in a better fit. After the stone is chipped-in to fit, start the spindle and bring the stone into the knife at a slow to moderate speed. One technique is to bring the stone in and out in 1 second intervals, making minor adjustments at each interval. Another technique is to bring the stone in and hold it in slight contact with the knives. Depth control adjustments are made while contact is being made. This technique is tricky as extended time of contact can cause the stone to glaze.
