Frequently Asked Questions About Reamers

What is a bridge reamer?

Sometimes called alignment reamers, bridge reamers are used to expand, debur, and finish off holes. They have tapered flutes that help the tool enter easily into roughly-cut holes.

What is a reamer used for?

Reamers are used for widening and finishing off drilled holes in metalwork. They are not used to create new holes, like a drill.

What is the difference between drilling and reaming?

Drilling is the process used to create a hole whereas reaming is purely used to finish the internal surface of a preexisting hole, not to create the hole itself.

What is the standard taper of the pin?

The standard diameter of a metric taper pin is 1:50.

What is a taper pipe reamer?

A taper pipe reamer is a cutting tool with multiple flutes. It’s used to resize and smooth out existing holes in metalwork. They have a left-hand spiral and a right-hand cut that drives in straight with the help of a T-handle tap. The end that cuts features a 45° chamfer to aid entry into the hole.

How do you use a taper reamer?

Taper reamers create tapered holes for taper pins. These pins have gears, cams, pulleys, and collars fitted to shafts. They are especially vital when using machines with rotating parts.

Where are taper pins used?

Taper pins are designed for screw machines and can aid the precise placement of dog and cam holders on camshafts. They can also be used on pulley holders and gears for main shafts.

How long can a reamer last for?

If used correctly, reamers can have an extended service life. As many as 30,000 holes can be reamed with a consistently high-quality finish. Reamed holes will often have a surface finish of approximately 10-25 µin. Ra.
