Chris' Tips

Chris' Tips
T-slot cleaners are designed for Bridgeport mills. It takes a few seconds on a grinder to reduce the size of the "T" to fit the slots on the mini mill.Combined drills and countersinks, commonly called center drills, are used to produce a center hole on a workpiece for turning between centers. Center drills are also used to start drilled holes. Because they are very stiff they don't have a tendency to wander.

Here are the sizes of center drills.

Number	Body Dia.	Drill Dia.	Length
1	1/8"	3/64"	1 1/4"
2	3/16"	5/64"	1 7/8"
3	1/4"	7/64"	2"
4	5/16"	1/8"	2 1/8"
5	7/16"	3/16"	2 3/4"
