Deep Hole Drilling Services

What is deep hole drilling?
A deep hole drilling is defined by its depth-to-diameter ratio (D:d), and typically holes greater than 10:1 are considered holes drill. Deephole services into metal has a range of applications across several industries, with its origins tracing back to the need for straighter, more accurate gun barrels, and expanding as other industries integrated deep-hole drilling processes to improve their own applications.
What does Innovex Engineering do for you?
We provide our customers with advanced Deepholedrilling solutions by producing tighter tolerances, better finishes and in tougher materials. Our management, engineers, and machinists work continually to improve our processes, procedures, and efficiencies. This provides to drill straight holes, with a good surface finish, in a wide variety of metals, in endless shapes. We’ve worked with every metal alloy family in every metallurgical state; castings, forgings, annealed, heat-treated, plated, coated, welded, metal-clad, powdered metal and more.
We’re so confident of our ability that we’ll lock in your price and delivery date right on the phone. Drilling is often not the whole journey for manufactured parts. We provide complementary services to save you lead-time and reduce supply chain complexity.
Innovex Engineering can offer Deep Hole Services as a stand-alone service or the complete manufacturing package, providing component processes to whatever stage you require. We provide 20 well-maintained Deep Hole drilling machines capable of running on 3 shifts basis.

• Precihole offers gun drilling capabilities from Dia. 2mm to 35mm, BTA from Dia. 16mm to 200mm
• We also offer Honing, Skiving and burnishing up to Dia. 200mm. Process Engineering, Tool Designing and Work Holding fixtures are all designed in-house by a dedicated team of talented engineers.

Rotating Tool

• Typically used for non-symmetrical components or round parts with off-centre holes
• Cutting speed is determined by tool spindle speed
• Drill drift can be significant when compared to rotating workpiece, or counter-rotating process

Rotating Workpiece

• Typically used for round parts with a deep, on-centre hole
• Cutting speed is determined by part, balanced to allow high rotating speeds
• Drill drift is reduced compared to the rotating tool only

Counter-Rotating Tool and Workpiece

• The ideal process for round parts with a deep, on-centre hole
• Cutting speed is determined by a combination of tool and workpiece rotation
• Provides optimal hole straightness and concentricity
