Reamers for Taper-Pin Holes

Shape holes to match the profile of taper pins. After drilling a hole that matches the size of the small end of the taper pin you want to install, use these reamers to taper and finish the hole.

Round Shank

Helix Flute

These reamers fit in the chuck of drill presses, turret lathes, and other machine and power tools, making them the most common shank type.

Helix Flute—Prevent clogging when removing excess material with helix flutes. They also leave a smoother finish than straight flutes.

High-Speed Steel—Durable and wear resistant, these are good for general purpose reaming in most materials.

Left-Hand Spiral—These reamers push chips downward as they cut, so they're often used in through holes.

Square Shank

Turn these reamers by hand with an adjustable wrench, straight-handle tap wrench, or pin vise (sold separately).

Straight Flute—The most common flute style, these reamers are suitable for a wide range of applications, but not recommended for holes with a keyway or other breaks in the surface.

Spiral Flute—Since these reamers clear chips better than straight flutes, they leave holes with a smoother finish. They're better for holes with breaks in the surface, such as a keyway, because they cut continuously across the breaks instead of moving in and out.

High-Speed Steel—Durable and wear resistant, these are good for general purpose reaming in most materials.

Left-Hand Spiral—These reamers push chips downward as they cut, so they're often used in through holes.

Reamer Sets for Taper-Pin Holes

Used for shaping holes to match the profile of taper pins, these sets include a variety of reamer sizes. Drill a hole that matches the size of the small end of the taper pin you want to install, and then ream to taper and finish the hole.

Square Shank

Turn these reamers by hand with an adjustable wrench, straight-handle tap wrench, or pin vise (sold separately).

Straight Flute—The most common flute style, these reamers are suitable for a wide range of applications, but not recommended for holes with a keyway or other breaks in the surface.

High-Speed Steel—Durable and wear resistant, these are good for general purpose reaming in most materials.

Left-Hand Spiral—These reamers push chips downward as they cut, so they're often used in through holes.
