Fast & Clean Holes, Every Time!

WoodOwl Ultra Smooth Auger Bits have a Tri-Cut design which consists of three precision-gound cutting edges and three flutes engineered for optimum performance. The unique head utilizes cutting spurs to scribe and bore extremely smooth holes with minimal blow-out. The precision-cut lead screw commandingly pulls the bit straight and true through the material without wandering.

Features:

  • 25-35% lighter than standard ship augers to reduce fatigue from extended use
  • PTFE coated to minimize friction and allow quick, easy cutting and chip ejection in the stickiest wood
  • Perfectly concentric, balanced and burr-free for accurate, smooth holes
  • Fully induction-hardened high-carbon steel for strength and durability
  • Includes a 7/16" quick-change shank

WoodOwl Ultra-Smooth Auger Bits

Three flutes and three cutter heads make the award winning WoodOwl Ultra Smooth Auger Bits a "triple threat". Precision engineered and manufactured in Japan, the patented Tri-Cut™ design and PTFE coating ensures the smoothest bore available from an auger bit. 

WoodOwl Ultra Smooth Auger Bits are the smoothest cutting auger bits available.

If you've ever used auger bits, you know that they have the potential to create messy holes and cause serious blowout—and if you ever used low quality auger bits, you've likely thenceforth avoided their use at all costs. I was in the latter category of woodworkers until I used WoodOwl Ultra Smooth Auger Bits.

A few years ago I needed to bore 1-1/4" holes crosswise through a 5" thick, 25" wide maple slab (don't ask).  I decided to purchase a couple 18" x 1-1/4" WoodOwl Ultra Smooths after reading some positive reviews. Past experience told me that I should leave plenty of waste on the sides of the slab because the entry and exit holes would need significant clean up. I figured I'd certainly overheat and break one before finishing, so I bought more than one bit. I was delighted to discover my assumptions were totally bogus. The bits are a joy to use. I proceeded to buy several more diameters in shorter, more practical lengths. WoodOwl's Ultra Smooth Auger Bits' unique features set them apart from others. If your opinion of auger bits is generally one of disdain, these might just change your mind.

Precision Machined in Japan

WoodOwl Bits are manufactured in Miki City, Japan. The area boasts a storied history of making high quality tools and hardware. They are not cast or forged, but milled and ground from solid S55C high carbon steel stock, ensuring perfectly concentric bits. Cutting edges are fully induction hardened to 58 HRC, maintaining a sharp cutting surface. Bits come hand sharpened from the factory and can be re-sharpened easily using a feather file. This manufacturing process produces a very sharp bit that has little to no wobble, and quickly drills accurately sized bore holes.

Patented Tri-Cut Design with Scoring Spurs

WoodOwl's patented Tri-Cut design features three flutes and cutting edges. Sharp spurs at the tip of each cutting edge score around the bore hole before the main body. The scoring cut cleanly separates wood fibers at the hole's perimeter minimizing tear out. Special design geometry isn't the only superlative setting this bit apart, however.

Every factor has been considered in the design of the WoodOwl Ultra Smooth Bits, creating an auger bit that outperforms most anything on the market.

More Than Just Innovative Bit Geometry

WoodOwl thought of everything when designing these bits. Very sharp lead screws immediately start into the wood when the drill starts to turn. The screws pull these bits straight and true through all types of wood with little wandering. A PTFE coating lessens friction, easily ejects chips, and protects from corrosion. This reduces torque and damaging heat buildup when driving the bit. Ultra Smooths are also up to 1/3 lighter than standard augers for increased safety and reduced fatigue without sacrificing strength. Finally, 7/16" hex shanks make these bits perfect for powered hand drills or manual braces without slippage. 

WoodOwl Ultra Smooths even produce clean results at the exit hole.

Available Individually or as a Set

Infinity Tools offers the WoodOwl Ultra Smooth Bits individually in 1/2"(101-901), 3/4"(101-902), 1"(101-903), and 1-1/4"(101-904) diameters. We also offer the bits as a money-saving set of all four individual sizes (101-905). All bits come in a convenient 7-1/2" length, most practical for normal use. They are packaged in individual plastic tubes, with a screw-on top and a protective tip cover.
