Description
Product Overview
The Large Cutting Broaches Set of 6 from PMC Supplies is a precision‑engineered tool collection designed specifically for jewelry makers, watch repair technicians, and small‑scale metal fabricators. Each broach is forged from high‑carbon alloy steel, heat‑treated for optimal hardness, and polished to a fine finish that minimizes friction during operation. The set includes diameters of 2.4 mm, 2.7 mm, 3.2 mm, 4.2 mm, 5.2 mm, and 6.2 mm, providing a comprehensive range for enlarging and aligning pre‑drilled holes before using taps and dies. Packaged in a sturdy, compact case measuring 10 × 6 × 1 inches, the tools are protected from impact and easy to transport to on‑site jobs or studio workstations. The design incorporates a tapered shank that fits standard hand‑held broach holders, ensuring a secure grip and consistent torque transfer.

Usage
These broaches excel in a variety of realistic scenarios. In a jewelry workshop, artisans use the 2.4 mm and 2.7 mm broaches to gently expand pilot holes in delicate gold or silver sheets, allowing subsequent tapping without cracking the material. For watchmakers, the 3.2 mm and 4.2 mm sizes are ideal for preparing holes in brass or stainless‑steel cases where precision is critical for screw‑in components. The larger 5.2 mm and 6.2 mm broaches serve larger gauge wires and structural components in prototype metal‑working projects, ensuring a clean, round hole that aligns perfectly with the chosen die. The set is compatible with standard hand‑broach holders, rotary tools with variable speed control, and bench‑mounted broaching machines, making it adaptable to both manual and powered workflows.

FAQ
What material are the broaches made from?
The broaches are forged from high‑carbon alloy steel and heat‑treated to achieve a hardness that balances durability with a sharp cutting edge, making them suitable for both soft and hard metals.
Can I use these broaches with a rotary tool?
Yes, the tapered shank design fits standard rotary‑tool broach holders. When using a rotary tool, select a low to moderate speed to maintain control and avoid overheating the workpiece.
Do the broaches require any special maintenance?
Regular cleaning after each use to remove metal filings, followed by a light oil coating, will keep the cutting edges smooth and prevent corrosion. Sharpening is rarely needed due to the high‑quality steel, but a professional sharpening service can be used if necessary.
Is the case compatible with other tool sets?
The case is designed specifically for this six‑piece set, but its interior compartments can accommodate similarly sized broaches or small accessories from other collections.
What is the warranty coverage?
PMC Supplies provides a one‑year limited warranty covering any manufacturing defects. If a broach becomes damaged under normal use, contact our support team for a replacement or repair option.
Overall, the Large Cutting Broaches Set of 6 offers a reliable, versatile solution for professionals seeking accurate hole preparation in fine metalwork. Its combination of material quality, comprehensive size range, and thoughtful packaging makes it a valuable addition to any jeweler’s or watchmaker’s toolkit.
