Hertel 16705063 Drill Bit Size 35 Solid Carbide 135 Point

Product Description

The HERTEL 16705063 is a screw machine length drill bit engineered for high-performance drilling in hard and abrasive materials. Built from solid carbide, it delivers the rigidity and heat resistance needed for demanding applications. The 135-degree split-point geometry reduces walking and minimizes the need for a center punch. At 1.875 inches overall length with a 0.875-inch flute length, this short-length design provides added rigidity over jobber-length bits. Wire gauge size 35 corresponds to a decimal diameter of 0.1100 inches. A slow spiral flute promotes chip evacuation in deep-hole and interrupted-cut scenarios. Intended for installation by machinists, tool-and-die professionals, and maintenance technicians working with precision metalworking equipment.

This bit is suited for drilling cast iron, nickel alloy, stainless steel, titanium alloy, and tool steel. The screw machine length format is commonly specified for use in CNC machining centers, drill presses, and turret lathes where stub-length tooling improves rigidity and reduces deflection. The bright uncoated finish makes it well-suited for applications where coating buildup or chemical interaction with workpiece materials is a concern. No coolant-through capability is present, so external coolant or cutting fluid should be applied at the cutting zone when running in heat-sensitive materials.

Key Features

• Solid carbide construction for maximum hardness and wear resistance in ferrous and exotic alloys
• 135-degree point angle reduces thrust force and virtually eliminates drill walking
• Slow spiral flute geometry aids chip control in deep or interrupted cuts
• Screw machine (stub) length provides greater rigidity and reduced deflection versus jobber-length drills
• Bright uncoated finish compatible with a wide range of cutting fluids and workpiece materials
• Right-hand cut with straight cylindrical shank for standard drill chuck compatibility

Compatibility

Designed as an OEM-style replacement or direct-use screw machine drill bit for standard straight-shank drill chucks and collet holders accepting a 0.1100-inch shank diameter. Suitable for drilling cast iron, nickel alloy, stainless steel, titanium alloy, and tool steel per manufacturer specification.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with drill press, lathe, or CNC operations. Ensure the spindle is fully stopped and power is disconnected before changing tooling. Secure the straight cylindrical shank firmly in a properly sized drill chuck or collet to prevent slippage under load. Apply appropriate cutting fluid at the cutting zone when drilling stainless steel, titanium, or tool steel to manage heat buildup, as this bit does not feature coolant-through capability.
