1-1/5in x 24in Auger Drill Bit for Wood - Extra Reach

Our review of the 1-1/5in x 24in auger drill bit finds it best suited for carpenters, landscapers and DIYers who need deep, clean holes in wood or composite materials; the single biggest reason to buy is its extra-long 24in length combined with a rigid tri flute center that maintains straightness during boring. The review focuses on real use: the hex shank holds firmly in a drill chuck, the self-positioning point starts holes accurately, and the precision-milled flutes move chips out quickly, which matters when drilling long runs or installing pipes.

Key Features

• 24in length: Provides extended reach for boring deep holes in joists, landscape timbers or when working from one side only.
• 1-1/5in diameter: Produces a large, consistent hole suitable for PVC pipes and large fasteners without excessive tearing of the wood.
• Tri flute solid center: Adds rigidity to keep the bit straight while maintaining a stable cutting action during long bores.
• Hollowed cutting flutes: Precision-milled hollows speed chip evacuation so holes stay cleaner and cutting heat is reduced.
• Wide lands and ground flutes: Help the bit track true and funnel chips inward for faster, cleaner cuts through both soft and hard wood.
• Reusable PVC tube: Simple, safe storage that protects the tip and makes transportation easier between job sites.

Who It's For

The bit is ideal for contractors and serious DIYers who routinely drill deep holes in lumber, plywood, MDF, landscape timbers or tree stumps and need the extra 24in reach. Its hex shank suits handheld drills and impact drivers that accept 3/8in hex, making it practical for on-site work where portability and speed matter.

It is not intended for metal cutting; users who only need small-diameter or short bits should look elsewhere. Also, those expecting consistently razor-sharp factory edges may encounter mixed sharpness reports and should be prepared to hone the cutting edges if optimal longevity is required.

Pros & Cons

Pros

• Extra-long 24in length gives access to deep or hard-to-reach drilling locations.
• Tri flute design and wide lands keep the bit tracking straight for accurate holes.
• Precision-milled hollow flutes speed chip clearance and help maintain cutting speed.
• Comes in a reusable PVC tube for safe storage and transport.

Cons

• Some users report variable sharpness out of the package, so occasional sharpening may be needed.
• Not suitable for metal drilling, limiting use to wood, plastic, drywall and composites.

Our Verdict

The 1-1/5in x 24in auger drill bit is a practical choice for anyone needing deep, clean holes in wood or composites; its length and tri flute rigidity deliver value for tradespeople and serious DIYers. While a few buyers note inconsistent sharpness, the bit's chip-clearing design, wide lands and sturdy 1045 carbon steel construction make it a cost-effective tool for repetitive boring tasks when occasional resharpening is acceptable.

Frequently Asked Questions

Can this bit be used in an impact driver?
The 3/8in hex shank allows use in many impact drivers and handheld drills that accept hex shanks, but check your tool specifications for compatibility.

Is this suitable for metal drilling?
No. The bit is designed for wood, plastics, drywall and composite materials and should not be used on metal.

How is chip removal handled when drilling deep holes?
The precision-milled hollow flutes and ground flutes behind the lands funnel chips inward to speed clearance and keep the outside diameter cleaner during long bores.
