| X-2642 | 1816-07-17 | Ezra L'Hommedieu | Norwich, CT | Single twist screw auger | Recovered |
Comments
L'Hommedieu claims that the cavity of this single-twist auger, being larger than for double-twist augers, allows chips to rise freely regardless of the depth of the bore - subject to the length of the twist. He also claims that this bit will work equally well with or without the lead screw.
