Deep Hole Boring for High-Tolerance, High-Depth Engineering Applications
At C.A Honemaster, we specialise in deep hole boring (DHB), offering precision machining solutions for components requiring exceptionally straight and accurate bores. With the acquisition of our deep hole boring facility in 2019, we seamlessly integrated this capability with our existing honing expertise, allowing us to deliver high-quality, precision-engineered components for industries that demand accuracy and reliability.
With the ability to bore holes up to 205mm in diameter and 3,500mm in length, our deep hole boring services support a wide range of sectors, including aerospace, oil & gas, hydraulics, and heavy engineering. Whether you need custom machining, oversized components, or precision deep bores, we have the expertise, equipment, and experience to meet your requirements.
What is Deep Hole Boring?
Deep hole boring is a specialised machining process used to create long, straight, and accurately dimensioned holes in solid materials. It is essential in applications where standard drilling or reaming methods are insufficient due to the required depth-to-diameter ratio.
At C.A Honemaster, our deep hole boring process ensures:
✅ Hole Diameters: From 10mm up to 205mm
✅ Maximum Depth: Up to 3,500mm (3.5 metres)
✅ Materials Processed: Steel, stainless steel, aluminium, brass, titanium, and exotic alloys
✅ Tight Tolerances: Exceptional precision for high-performance applications
✅ Straightness & Concentricity: Ensuring minimal deviation over long distances
By combining deep hole boring with our honing expertise, we deliver flawless bore finishes that meet the most demanding industry standards.
