Flexible Cylinder Hones for Steel and Stainless Steel

With a silicon carbide abrasive, these hones are the best choice for steel and stainless steel. They’re sharp enough to remove material while leaving a cross-hatch patterned finish that retains lubricant. Hones have abrasive-embedded balls on flexible spindles to press against the inside of cylinders. They perform best on steel and stainless steel but are also a good all-around option for other materials. Hones are slightly oversized for maximum contact with surfaces. When your cylinder ID falls between two sizes, order the larger hone. Use them with portable drills, drill presses, and CNC machines. Hones should be rotating when inserted or removed from cylinders. We recommend using them with honing oil to keep the abrasive surface free of debris.

Twisted Shank—Snip the shank to shorten the length of your cylinder hone.

Hex Shank—Required for cylinder IDs of 9" or larger.

Grit—Grit is identified by the color on the tip, except 120-grit hones are unmarked.

Easy-Adjust Rigid Cylinder Hones

Control the pressure you apply to surfaces with a turn of the adjustment knob to achieve your desired finish. These hones have spring-loaded arms that push the abrasive stones against cylinder walls. Rigid stones repair cylinders that are out-of-round, tapered, or otherwise misshaped. Use with portable drills, moving the hone up and down to leave a cross-hatch pattern that retains lubricant. The shank flexes to reach around curves or into spaces where you can’t keep the drill parallel to the cylinder. We recommend using hones with honing oil to keep the abrasive free of debris.

Flexible Cylinder Hones for Soft Metals

Twisted Shank

Prevent clogs when honing soft metals, such as aluminum. These hones have aluminum-oxide abrasive balls that resist buildup. Mounted on flexible spindles, the balls press against the inside of cylinders. They remove material and leave a cross-hatch patterned finish to retain lubricant. Hones are slightly oversized for maximum contact with surfaces. When your cylinder ID falls between two sizes, order the larger hone. Use with portable drills, drill presses, and CNC machines. Hones should be rotating when inserted or removed from cylinders. We recommend using them with honing oil to help clear debris from the abrasive.

Twisted Shank—Snip the shank to shorten the length of your cylinder hone.

Grit—Grit is identified by the color on the tip, except 120-grit hones are unmarked.

Rigid Cylinder Hones

Fix misshaped cylinder walls, including those that are out-of-round or tapered. These hones have rigid abrasive stones that remove small amounts of material. They’re adjustable, so you can size them to your cylinder in micrometer increments. Clip two stones and two felt cleaning wipers onto the holders. Then, turn the knob to expand until the stones press against the cylinder. Use with portable drills, moving the hone up and down to leave a cross-hatch pattern that retains lubricant. We recommend using these with honing oil to keep the abrasive free of debris.

Flexible Cylinder Hones for Hard Metals

Twisted Shank

A hard abrasive removes material from metals such as hardened steel, titanium, and iron. It also leaves a cross-hatch patterned finish to retain lubricant. These hones have abrasive-embedded balls mounted on flexible spindles that press against the inside of cylinders. Hones are slightly oversized for maximum contact. When your cylinder ID falls between two sizes, order the larger hone. Use with portable drills, drill presses, and CNC machines. Hones should be rotating when inserted into or removed from cylinders. We recommend using them with honing oil to keep the abrasive free of debris.

Boron Carbide Abrasive—Harder than standard abrasives such as silicon carbide and aluminum oxide, boron carbide will hone hardened steel, titanium, and iron. It's not as hard as diamond, however, so it can't hone carbide or ceramic.

Diamond Abrasive—Our hardest, longest-lasting abrasive will hone any material, even ceramic and carbide.

Twisted Shank—Snip the shank to shorten the length of your cylinder hone.

Abrasive Material—Abrasive material is identified by the color on the stem.

Grit—Grit is identified by the color on the tip, except 120-grit hones are unmarked.

Rigid Cylinder Hones for Machine Tools

Turn your drill press, lathe, mill, or CNC machine into a precision honing system. These hones finish cylinder diameters as small as 3/16" to within a 0.001" tolerance. They correct out-of-round holes, slots, keyways for shafts, bushings, and dowel pins. To retain lubricants, they leave a cross-hatch pattern on cylinder walls. Install the hone’s driver in your spindle and guide or program your machine to move the hone up and down to create the pattern.

Drivers

Use these drivers to adjust honing stones forward or backward on a tapered mandrel for a precise cylinder fit. One driver pairs with all the mandrels—just swap the mandrel to hone a different size.

Honing Kits

Each kit contains a mandrel, two honing stones, and a truing sleeve. The mandrel holds the honing stones and snaps into a driver with a quick twist. Since the mandrel doesn’t touch the work surface, it won’t wear out and need replacing. The truing sleeve conditions the honing stones so they’re perfectly cylindrical and concentric to the mandrel.
