Contract Machining & Manufacturing Co. delivers precision machining services for the drilling industry, specializing in parts that support rotary drilling and down the hole hammer drilling operations. With over 40 years of experience, we manufacture components that meet strict quality standards and perform reliably under demanding conditions. Our focus is on producing durable, high-precision parts for rotary drilling systems, including drill steel, sub adapters, rotary deck bushings, bit rings, and related accessories. Every component is machined to your exact specifications, ensuring dependable performance for mining, quarrying, and construction applications.
Rotary Drilling Components
We produce components critical to rotary drilling operations. These parts are engineered to withstand heavy loads, high rotational forces, and extreme wear.
- Rotary Deck Bushings – Keep the drill string aligned and stable during drilling operations. Manufactured to precise tolerances, they reduce wear on the rotary system and support smooth rotation.
- Bit Rings – Assist in the installation and removal of drill bits, keeping operations efficient and safe. Each bit ring is fabricated from durable alloys that resist cracking or deformation.
- Drill Pipe and Drill Steel – Engineered for strength and reliability. Our drill steel withstands the high-impact conditions of down the hole drilling and maintains integrity under repeated use.
- Sub Adapters – Connect drill steel to bits securely. Precision machining guarantees a tight fit, preventing failure in high-stress environments.
- Lifting Bells and Hoisting Plugs – Essential for safe handling and attachment of drill steel. Designed to meet operational standards, they improve efficiency during rig assembly and maintenance.
Each component is inspected for quality and adherence to specifications, giving clients confidence that every part will perform as expected.
Down the Hole Hammer Drilling Products
For down the hole hammer drilling operations, we focus on parts that maximize drilling speed and reduce equipment wear.
- Drill steel that endures high-impact conditions.
- Sub adapters that maintain alignment and secure attachment between drill steel and bits.
- Components engineered for easy replacement and minimal downtime, keeping drilling projects on schedule.
Our parts are compatible with standard DTH systems and can also meet specific client requirements for specialized rigs.
