What is 1613 PCD? A Complete Guide to Pitch Circle Diameter

In the world of industrial tools and components, precise measurements are everything. One critical specification you’ll encounter, especially for items like drill bits, hole saws, and wheel hubs, is the Pitch Circle Diameter, or PCD. But what exactly does 1613 PCD mean? This guide will break it down for you.

Understanding Pitch Circle Diameter (PCD)

Pitch Circle Diameter is the diameter of an imaginary circle that passes through the center of all the bolt holes or studs on a mounting. It’s a standardized measurement that ensures components fit together perfectly. For example, a wheel must have the exact same PCD as the vehicle’s hub for a secure fit.

Decoding the 1613 PCD Specification

The notation “1613 PCD” specifically refers to a two-bolt pattern. Here’s the breakdown: The first two digits (“16”) represent the Pitch Circle Diameter in millimeters. The last two digits (“13”) indicate the distance between the centers of the two bolt holes, also in millimeters. Therefore, a 1613 PCD means the bolts are arranged on a 16mm diameter circle, with 13mm separating the two holes.

Common Applications of 1613 PCD

This specific PCD is commonly found in various cutting and drilling tools. It’s a standard for many industrial-grade hole saw arbors and pilot drill assemblies. Ensuring you have the correct PCD is crucial for tool compatibility, performance, and safety. For a specialized application, you can explore a 1613 PCD ridge-shaped PDC cutter designed for demanding cutting operations.

How to Measure PCD Accurately

For a two-bolt pattern like 1613, measuring is straightforward: simply measure the center-to-center distance between the two holes. That distance is the second number in the PCD code. Always use precise calipers for an accurate measurement to avoid mismatches.

Frequently Asked Questions (FAQ)

Q: Is 1613 PCD a common standard?
A: Yes, it is a widely used standard for many tool mounting interfaces, particularly in hole saw and drill bit shanks.

Q: Can I use a tool with 1613 PCD on a different arbor?
A: No. The PCD must match exactly. Using an incorrect PCD can lead to tool wobble, improper cutting, and potential safety hazards.

Q: Where can I find tools with this specification?
A: Many industrial tool suppliers stock components with 1613 PCD. Always check the product specifications before purchasing.
