2. Punch (tool) - Wikipedia

   en.wikipedia.org/wiki/Punch_(tool)

   A drift punch is constructed as a tapered rod, with the hammer acting on the large end of the taper. The long end of a drift punch is placed into the semi-aligned bolt holes of two separate components, and then driven into the hole. As it is driven in, the taper forces the two components into alignment, allowing for easy insertion of the fastener.

3. Spike maul - Wikipedia

   en.wikipedia.org/wiki/Spike_maul

   Almost all spike mauls take a standard 36-inch (90 cm) oval eye sledge hammer handle, which is frequently replaced through the course of heavy use. It is common practice in many locales to cut down the long handle to about 28 inches (70 cm). This makes the maul more convenient when used only to "set" spikes for a powered spiker.

4. Drift pin - Wikipedia

   en.wikipedia.org/wiki/Drift_pin

   In metalworking, a drift pin, drift pin punch, simply drift, is the name for a tool used for localizing a hammer blow. A drift is smaller in diameter than the hammer face, thus concentrating the force into a smaller area. A drift is also used where the surrounding surfaces need to be protected from the hammer blow.

5. Punching - Wikipedia

   en.wikipedia.org/wiki/Punching

   Die and punch shapes affect the force during the punching process. The punch force increases during the process as the entire thickness of the material is sheared at once. A beveled punch helps in the shearing of thicker materials by reducing the force at the beginning of the stroke. However, beveling a punch will distort the shape because of ...

6. Impact driver - Wikipedia

   en.wikipedia.org/wiki/Impact_driver

   A manual impact driver (for use with hammer) with screwdriver bits and adapters. An impact driver is a tool that delivers a strong, sudden rotational force and forward thrust. The force can be delivered either by striking with a hammer in the case of manual impact drivers, or mechanically in the case of powered impact drivers.

7. Automatic center punch - Wikipedia

   en.wikipedia.org/wiki/Automatic_center_punch

   The hammer has a hole through its center that the top of the punch sits in, and holds the top of the punch centered. The sliding block has a hole through it that, when reset, is misaligned with the hole through the hammer. When the body is pressed to the trip point, a taper in the body forces the block sideways until the hole in the block is ...
