Laps and Lapping Tools Information Laps and lapping tools are used for precision surface finishing, often in conjunction with loose abrasive compounds. Lap is a soft material that is charged with an abrasive and is used for cutting harder material.A lapping machine uses a charged lead piece as lap for cutting a hardened steel piece. lapping ring tool is a tool used to set the ring properly in the piston grooves. Other laps and lapping tools are commonly available. There are several ways in which laps and lapping tools function.

How the middle finger became an offensive gesture is another story altogether.

Hand â Bones, Ligaments, Muscles & Conditions Intrinsic muscles only act on the fingers. The extrinsic muscles are the long flexors and extensors, which run from the forearm into the hand, providing strength to the hand and wrist. The flexors enable the fingers to bend while the extensor muscles are used to straighten the fingers.
