…slate, granite, schist, and limestone … are difficult or even impossible to flake. Toolmakers using these materials had to start by laboriously pecking the rock into the desitred shape, then finish the tool by grinding and polishing. Most of these early ground stone tools were made for woodworking —items like axes, chisels, and adzes.

For shallower holes, a standard hammer drill will work. Step 2 - Measure and Mark. Mark the drill holes carefully on the wall. Measure twice, and mark with chalk in a contrasting color from the wall. It is difficult to repair a mistake in drilling on a stone wall, so make certain you have the holes in the right place before you begin.
Make sure the drill you are using is a variable speed drill, rather than a hammer drill, which may damage natural stone surfaces. If you are drilling through a limestone-tiled wall, immediately stop drilling when you hit a stud behind the wall. Replace the drill bit with a more appropriate one before continuing.

Limestone is a naturally occurring stone that is found in abundance throughout much of the United States. It is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs. The major materials in Limestone are the minerals calcite and aragonite, which are different crystal forms of calcium ...
Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone has long fascinated earth scientists because of its rich fossil ...
air hammer in some quarries had reached eight to ten hours a shift and by 1917 the mallet and hammer had been discarded everywhere. The limestone industry consisted then of some 4000 employees in 40 mills and quarries and many of the fine buildings in Washington and New York were built with this white Indiana limestone. Received 17 March 1983
Limestone has been a valuable resource since Missouri became a state. In early open pit operations, limestone was mined and crushed by hand and removed from the quarries by mules, carts and tramways. Limestone is now mined using surface and underground methods. Surface quarrying is the most common method of producing limestone in Missouri.

Materials. A hammerstone is made of a material such as sandstone, limestone or quartzite, is often ovoid in shape (to better fit the human hand), and develops telltale battering marks on one or both ends. In archaeological recovery, hammerstones are often found in association with other stone tool artifacts, debitage and/or objects of the hammer such as ore.

A report in Creation Ex Nihilo (Mackay, 1983) stated the hammer was "in limestone dated at 300 million years old" (which would make it Pennsylvanian). A subsequent CEN article (Mackay, 1984) stated that the hammer was in "Ordovician rock, supposedly some 400 million years old" (although that age would make it Devonian, not Ordovician).
