150mm Diamond Hole Saw Extension Rod – Precision Adapter for Deep Hole Core Drilling

The Diamond Hole Saw Extension Rod (150 mm) is an industrial-grade drilling accessory designed to extend the working depth of compatible diamond core drill bits and hole saws. Ideal for deep coring through thick stone countertops, masonry blocks, tiles, glass, and ceramics where standard drill shanks cannot reach.

Key Features

• Extended Working Depth: Adds 150 mm of working reach for deep hole drilling and thick slab coring.
• High Concentricity & Stability: Precision-machined solid alloy steel minimizes vibration and drill bit wobble at high rotation speeds.
• Universal Compatibility: Engineered for seamless connection with standard diamond core drill bits (6 mm to 100 mm).
• Durable Construction: Heavy-duty, corrosion-resistant steel built to withstand wet drilling conditions and high torque.
