Reamers for Taper Pipe

Use these reamers to shape and finish a hole to a tapered pipe size before tapping.

Square Shank

Spiral Flute

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

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.

Reamers for Deburring

Smooth the inside and edges of holes with these reamers. Often used to finish holes in sheet metal or to remove burrs from the ends of cut pipe and conduit, they're also known as repairmen's reamers.

Round Shank

Spiral 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.

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.

T-Handle Shank

Spiral Flute

No additional tools required, these reamers have an integrated handle that's easy to grip and turn.

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

L-Handle Shank


Straight Flute	Spiral Flute

Turn these reamers with the long ratcheting handle, which provides more leverage than a T-handle.

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.

Hardened Steel—Typically more economical but less durable than high-speed steel, these are for general purpose reaming.

Right-Hand Spiral—These reamers pull chips upward as they cut, so they're often used in blind holes.

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

Changeable-Blade Ratcheting Deburring Scrapers

To save time and effort, these scrapers have a ratcheting mechanism to smooth the edges of tubes and holes without removing and repositioning the scraper. Replace the blade when it’s dull, or change it with a different blade style. Adjust the length of the scraper to easily reach your workpiece.

Deburring Blades


Style G	Outer Tube Edge

Choose from a range of blade shapes to scrape burs from flat surfaces to tube edges. Insert blades with a 0.1" dia. shank into a changeable-blade deburring scraper. For blades without a shank, they require a blade holder (sold separately); they are only for use with adjustable-length deburring scrapers, which secure the blade holder.
