The Knuth KSB 40B is a rigid box-column drill press engineered for demanding drilling, reaming, and thread-cutting applications. Featuring a drilling capacity of 1.57 inches in mild steel, this machine delivers maximum axial feed force of 16,000 lbf, supported by a powerful 4 HP main drive motor with 3,098 ft·lb spindle torque. The spindle accommodates MT 4 tooling and operates across a broad speed range of 31.5 to 1,400 rpm, providing finely stepped gears for precise machining parameters on large bores. The machine's torsion-proof box-column design ensures unwavering stability and superior rigidity, eliminating vibration and deflection during operation. The work table measures 19 x 22 inches with three 18 mm T-slots and can be positioned vertically along with the drill head for optimal machining height. Vertical head travel spans 8 inches with a quill stroke of 10 inches, while the throat depth reaches 13 inches. Standard equipment includes a coolant system with 6.6 gal/min flow rate, automatic tapping unit, and rapid feed capability. The machine weighs 2,750 lbs with overall dimensions of 40.94 x 35.83 x 99.61 inches, providing a substantial footprint suited for production environments. Oil-bath lubrication and 9-step feed and speed gears ensure reliable, maintenance-efficient operation for industrial drilling tasks requiring precision and consistency.
