Bowers Holmikes

The Holmike is a direct reading internal micrometer which measures bores and bottoms of blind holes.
Sizes over .250"(6mm) feature three measuring contact anvils which are self-centering for true readings. Sizes under .250"(6mm) use a 2 point "split-cylinder" design. Holmikes over 1" use two sets of anvils so that only six sets are necessary to cover the range from .080" to 4". Sizes available from
.040 to 12"(1—300mm). All micrometer anvils over 1/2" (12.5mm) are tungsten carbide. All sizes have blind bore anvils except 1/4"- 1/2" sizes.
