Other information/spec
- 6” Diameter x 33-1/2" Length Steel Chisel Bit for Cable Tool - For cable tool drilling 6" diameter holes in clay and other geological formations. 2-1/4" x 3-1/4" male thread. - Around 33-1/2" length. - A regular bit, from a worm's eye view, looks like an H with the sides bent in a circle. - This gives star bits four cutting edges rather than the two on a regular bit, though they are smaller. - The design of a star bit helps it drill straighter in slanted formations. - For extreme conditions, manufacturers can also twist star bits just like regular bits. - Again, we would want a right-hand twist to use with left-lay drilling line. - Star bits, despite their construction, weigh just about the same as a regular drill bit of the same length. - Distance across the four wings is just about the same as the body diameter of a regular bit. - Although a special purpose bit, drillers could use it every day in some geologies and conditions. - Presumably American manufactured with carbon and/or alloy steels, but unsure if this is Acme, Spang, Gill Rock Drill, Ideco, Trident, Rampp, O.W.S. Co., Keystone or maybe another historical tooling manufacturer. - If you require thread protector(s) on tool joint(s) add another $15. - Located in Mifflinburg, PA USAShow more
