Tarrier Drill, also known as the Star Drill.

Some years ago I was helping convert an old Railway Station in Whitstable into a "Social Club" - Money was short and we only hired Kango Hammers when we had to.

We had to cut a 6" diameter hole in some raileay "blue" engineering bricks to run the beer pipes into the bar area. A local metal worker converterd 2 railway Crowbars into Star drills and away we went. Christ it hurt, not so much the misses with the sledge but the shock on the wrists and arms holding and twisting the drills.

No I've some respect for those who could and did drill through rock and coal with "Star Drills"

Ah the things you have to do at times !
