COUNTERSINKS

Countersinks are use designed to produce accurate center holes in components which require matching between centers.

ADJUSTABLE COUNTERSINKS

Adjustable Countersinks
Carbide Tipped Adjustable Drill Countersinks are designed to cut bevels in wood and plastic for wood screw heads #4 to #10. They attach to the drill with two set screws and can be adjusted up and down the drill for any length from a #4 to a #10 wood screw.

DRILL COUNTERSINKS

Drill Countersinks for Wood Screws
Drill Countersinks are designed to cut bevels in wood and plastic for wood screw heads. They attach to the drill with two set screws and can be adjusted up and down the drill for any length of wood screw. All Drill Countersinks have 4 flutes.

FLUTED COUNTERSINKS

Zero Flute (Deburring) Countersink
Zero Flute Countersinks are designed for countersinking and deburring operations. The single cutting edge removes stock quickly and prevents chatter. They can be resharpened by using an Axial Relieving Fixture or by using a small mounted grinding wheel and inserting it into the hole.
Single Flute Countersink
Single Flute Countersinks should be used when multi-flute countersinks chatter or the hole is too small for a multi-flute countersink to enter. Use for machine and portable work when operating at higher speeds. Drilled hold should be at least 10% of the diameter of the countersink.
Three Flute (Center Reamer) Countersink
Three Flute Countersinks should be used at a slower (1/2 to 2/3 the speed used for drilling) speed. Recommended for machine and portable work. Because of their centering ability they are widely used in portable applications.
Four Flute (Machine) Countersink
Four Flute Machine Countersinks have a longer shank for use in Turret lathes and for screw machine works.
Six Flute (Chatterless) Countersink
Six Flute Countersinks are designed for fast shearing cuts.

INDEXABLE COUNTERSINKS

Indexable Countersinks
Indexable Countersinks are designed with a positive rake for smooth cutting without chatter. No tool resharpening needed. Uses standard triangle inserts that come with countersink.

LONG REACH (EXTRA LENGTH) COUNTERSINKS

Long Reach Countersinks - Single Flute
Single Flute Long-Reach Countersinks are used for difficult to reach tool and die work. The single flute is designed for chamfering and deburring holes too small for multi-flute countersinks.
Long Reach Countersinks - Six Flute
Six Flute Long-Reach Countersinks are used for difficult to reach tool and die work requiring fine finish cuts. The six cutting edges quickly center in hole and produce a smaller chip load.
