Hole Openers

Stabil Drill hole openers help create a clean, high-quality hole in a way that minimizes the number of tool trips.

Hole openers are fixed-diameter tools designed for enlarging pilot holes or other large-hole applications. At Stabil Drill, our BHA experts can help specify the perfect design for strong hole creation. All of our hole openers are engineered and made in-house from AISI 4145H fully heat-treated alloy.

We offer hole openers in a variety of designs, with optional carbide-milled teeth and inserts. Our tools feature forged bodies, thick collector boxes, cast iron mounts and 24/32 Series 95 Smith jets. They also come with hard-facing that helps optimize hole development and are engineered to enable cutter changes in the field.

Integral Body Sealed Bearing Hole Opener

Featuring solid, one-piece construction and either milled tooth or tungsten carbide cutters, these tools deliver the stability and reliability you need to execute the drill plan with confidence. Accommodates solid or circulating bullnoses.

Collector Box Style

This design optimizes hole cleaning through use of a box collector that creates even fluid flow directly onto the unit's cutters. Accommodates up to 60”, and features either three or four cutters. Custom sizes and designs available; ask your Stabil Drill representative for details.

Devil Drill

With no moving parts that could fail and create unnecessary trips or NPT, the Devil Drill wipes the hole clean for easy casing installation to the bottom. Often deployed directly after horizontal mud motor runs, the Devil Drill™ features blade edges tipped with tungsten carbide chips.


Simultaneously allows hole enlargement while drilling. Allows underreaming of a hole larger than the ID above the casing.

Spiral Key Seat Wiper

Designed to eliminate key seat issues, this tool has no moving parts and it runs while you continue to drill— eliminating the need for a special trip to eliminate tight spots.
