Set the tapered bottom end of the tap into the top ofthe drilled hole. Keep the tap perpendicular to the metaland keep the handles of the wrench parallel to the metal.Slowly turn the wrench clockwise, pushing down with firm pressure.The tap will begin to cut threads into the inside of thehole.
Also to know is, how do you make threaded holes in metal?
Coat the tap with cutting and tapping fluid. Place a bitof fluid on / in the hole to be tapped. Align the tapwith the drilled hole in the metal. Startthreading the hole in the metal by turning thetee-handle tap wrench clockwise for a right-hand threadedhole or counter-clockwise for a left-hand threadedhole.
- Reference a tap chart to determine the drill bit size requiredfor the threaded hole.
- Secure the drill bit in a drill motor.
- Place the point of the coated drill bit on the aluminum.
- Secure a tap in the handle of a tee-handle tap wrench.
- Turn the tap handle clockwise to thread the tap into thehole.
Regarding this, how do you thread a steel rod?
How to Thread a Steel Rod
- Secure the steel rod into a bench-mounted vise with one end ofthe steel rod pointed toward the ceiling.
- Insert a blade of a thread gauge inside of the hex nut.
- Select a die from a die set that matches the size stated on thethread gauge blade.
- Insert the flat side of the die into the socket of the diewrench.
Drill at a Slow Speed In general, it's a good idea to drill throughmetal using as slow a speed as possible using a drillbit for metal. Hard metals like steel and largerdrill bits require even slower speeds. With a small twistbit (1/16 in. to 3/16 in.), you can drill through mostmetals at 3,000 rpm.
