AG036 Full Set of 13 Russell Jennings No.100 Fine Thread Augers


These are what all the others are trying to copy, a complete set of original Russell Jennings crucible steel No.100 extension lip augers, in exceptional condition, dating from before the company was acquired by Stanley in 1944.

All the bits are in superb order, the lead screws are perfect and several of the bits don't look to have ever been sharpened from new. One or two have jaw marks on the shanks (wiggling the bit and retightening is a good habit to get into) but apart from that they are as new.

In 1855 Russell Jennings patented his double twist bit with cutting spurs. Widely regarded as the best bits for use in hardwoods, the fine thread version soon became popular with furniture makers and remains so to this day.

The double twist rests evenly on opposite sides of the hole, so the bit naturally wants to stay straight. The cutting lips release a circle of timber just ahead of the main cutting edge so that the main edges can plane out the waste with ease.

As with all self feeding augers, the best way to get a clean exit hole is to clamp a block of scrap on the exit side so that the surrounding timber is backed up and the lead screw still has something to bite into. 

1/4 to 1” by sixteenths

Supplied in a new British made 18 pocket canvas auger roll.

These augers are pre-owned and not covered by our Lifetime Warranty - please see Terms and Conditions.

In Jennings own words:

"The bits in this set are our Fig 100 and have our standard double thread point, and are unsurpassed for accurate work in seasoned woods not extremely gummy or hard, it is the thread used by cabinet makers."
