M.a. Ford. 30017300 Circuit Board Drill Bit Size 17

Product Description

The M.A. FORD. 30017300 is a solid carbide circuit board drill bit designed for precision drilling in electronics manufacturing and PCB fabrication. Built to wire gauge size 17 with a decimal diameter of 0.1730 inches (4.39 mm), it features a 118-degree drill point angle and a fast spiral flute geometry with a 35-degree helix angle. The tapered web configuration adds rigidity and improves chip evacuation during high-speed drilling. With a 0.75-inch flute length and a 1.5-inch overall length, this bit is sized for compact, controlled cuts in tight-tolerance applications. It is part of M.A. FORD.'s Series 300 heavy-duty lineup and is installed by CNC operators, precision machinists, and PCB production technicians.

This drill bit is intended for use in circuit board drilling operations and general precision machining applications. The solid carbide construction and fast spiral design make it suited for cutting cast iron, non-ferrous metals, steel, and plastics. It is commonly used in CNC drill presses and high-speed spindle setups where consistent hole diameter and clean entry and exit are required. The right-hand cutting direction and uncoated finish are appropriate for applications where lubrication or coolant is applied at the spindle.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• 118-degree drill point angle for accurate positioning and reduced walking
• Fast spiral flute design with 35-degree helix angle promotes efficient chip removal
• Tapered web configuration adds core strength and stability during drilling
• Wire size 17 decimal diameter of 0.1730 inches (4.39 mm) for close-tolerance holes
• Uncoated finish compatible with coolant-assisted and lubricated cutting environments
• Heavy-duty grade rating for demanding production drilling cycles

Compatibility

Designed as an OEM-style precision drill bit for use in CNC and manual drill presses accepting a 0.1730-inch (4.39 mm) shank diameter. Suitable for circuit board drilling setups and general-purpose machining operations in cast iron, non-ferrous metals, steel, and plastics.

Installation Notes

This bit should be installed by a qualified CNC operator or machinist using a properly sized collet or chuck rated for the 4.39 mm shank diameter. Ensure the spindle is fully stopped and locked out before changing tooling. Verify runout tolerance and collet condition before use, as carbide bits are sensitive to lateral loading. Follow the machine manufacturer's recommended feed rate and spindle speed for the workpiece material to avoid bit fracture.
