Three-hole step drill bit

The Westward 6EXN6 is a high-speed steel step drill bit with an oxide coated finish. It creates three precise hole sizes in a single pass through thin material. The straight shank features three flats for secure chuck grip. This accessory is designed for use with power and pneumatic drills.

Sheet-metal fabricators and maintenance technicians

This bit suits users who need to drill 1/2 in, 7/8 in and 1-1/8 in holes in sheet metal, ductwork or electrical enclosures. It is not for buyers who require more than three diameter steps or who need to drill holes deeper than 4.5 mm. Workers needing a split-point tip for self-centering without a pilot hole should look at a different design.

4.5 mm maximum drilling depth

The bit can only penetrate material up to 4.5 mm thick before the step shoulders bottom out. This limit decides whether the tool will reach through your workpiece or stop short. Check the thickness of the metal, plastic or composite you plan to drill before purchasing. Proposition 65 warnings apply to this product.

Questions about this item

How do I confirm the Westward 6EXN6 step drill bit is cutting correctly after I start drilling?

The bit should produce clean, round holes at each of the three step diameters — 1/2 in, 7/8 in and 1-1/8 in — without grabbing or excessive vibration, and the oxide coating should remain intact on the flutes.

What comes with the Westward 6EXN6 step drill bit and what must I supply separately?

The package contains only the single step drill bit made of high-speed steel with an oxide finish; you will need a compatible drill with a 3/8 in chuck and suitable cutting fluid or lubricant for the material being drilled.

Which version of the Westward 6EXN6 should I choose for my application?

This model is offered in one configuration — a three-hole step drill bit covering 1/2 in, 7/8 in and 1-1/8 in diameters with a 3/8 in shank — so select it when those exact step sizes match the holes you need to drill.
