Product Details
Lapping Stick
Hard Wood Stick
The laminated boards are combined according to the directionality of the wood grain, and are fully adhered with resin bonds after high-pressure compression. Engis stick is easy to shape and is characterized by its shape that does not easily collapse. Accurate diamond lapping can be done by hand processing the details of the mold.
Soft Wood Stick
/ Very Soft Stick
Sticks are designed for semi-finishing or final finishing.
Can be used with fine diamond compounds to achieve a mirror finish.

Polishing Bob
Felt Bob (Meddium / Hard)
All felt bobs are made of natural wool and are soft and tough.
Various types are available according to various mold finishes.
Wood Bob (Soft / Hard)
Using the high-pressure compression method, thin sheets of plastic are layered and laminated. The wood grain direction is vertical, so it is durable and always maintains hardness.
15µm or less is suitable for the diamond compound used together.
There are two types of soft / hard in the following shape.

Helical lap
Lapping tools from Helical Lap & Manufacturing Co. provide a simple and economical solution for producing extremely fine tolerances and accuracies in bores and cylindrical parts.
Helical Laps can adapt to be used on almost any machine with a rotating spindle, such as a lathe, drill, or honing machine.
Helical Laps are highly versatile tools that can be used in a wide range of materials and applications.
Helical ID and OD Laps are manufactured from a proprietary grade of annealed grey cast iron with a grain structure designed to optimize the abrasive charging of the tool. The lap incorporates a helical slot to allow for expansion and contraction of the tool.
Helical Laps are primarily finishing tools to bring parts to size, reduce the rough peaks of a surface, and correct common imperfections in bore and cylinder geometry such as roundness, bellmouth, and barrel shape.
The tools are used with a lapping compound (diamond, aluminum oxide, silicon carbide, boron carbide, garnet) and typically, only a small amount of material is removed. The tools should always be ordered to the true ID or OD of the part to be worked, and then they are manufactured with the correct starting size.
