The flexible shank on these hones gives you access to hard-to-reach spots. A knurled adjustment knob lets you adjust the pressure applied to the side of the cylinder to achieve your desired finish. The square end can hone to the bottom of step-cut and closed-end holes. Use on portable drills. We recommend using them with honing oil to keep the abrasive surface clean.

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.

A long-lasting diamond abrasive is embedded in balls at the ends of flexible spindles that press against the inside of a cylinder to remove material and leave a smooth, even finish. These hones are slightly oversized to maximize contact with the work surface. 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 surface clean.

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.
