Aircraft Counterbore 13/32″ Carbide Tipped Shank 1/4″ Super Tool

Description

Product Overview

The Super Tool 13/32″ aircraft counterbore is engineered for high‑precision aerospace applications where space constraints demand a reduced shank profile. Constructed from premium carbide, the cutting tip maintains sharpness even under prolonged high‑speed operation, delivering consistent material removal and a clean, burr‑free finish. The tool’s overall length of 2.75 inches and a compact 0.4‑inch diameter shank enable seamless integration into CNC machines, manual drill presses, and specialized aircraft maintenance rigs that cannot accommodate larger shank diameters.

Designed with a 1/64″ corner radius, the tool provides a smooth transition from the pilot hole to the final counterbore, reducing stress concentrations and extending tool life. The tolerance on the tool diameter is +0.001″/‑0″, while the shank tolerance is +0″/‑0.001″, ensuring a precise fit that minimizes runout and vibration. The reduced 1/4″ shank diameter is especially valuable for legacy equipment that was originally built for smaller tooling, allowing technicians to retrofit modern counterboring capabilities without costly machine upgrades.

Key specifications include a minimum cut diameter of .156″ due to the pilot hole requirement, a pilot hole diameter of 1/8″ for optimal guidance, and a set screw mechanism that securely holds either a pilot or a drill bit in place. This flexibility enables users to adapt the tool for a variety of spot‑facing and counterboring tasks, ranging from creating mounting points for avionics to preparing surfaces for fastener installation. The tool’s lightweight construction—just 0.01 ounces—facilitates rapid tool changes and reduces operator fatigue during extended maintenance sessions.

Manufactured in the United States by Super Tool, the counterbore adheres to strict quality control standards, ensuring each unit meets the exacting demands of the aerospace industry. The product’s ASIN B00PM4IK5Q and its ranking as #28 in the Counterbores category reflect its popularity among professional technicians who require reliable, high‑performance tooling. With a price point of $94.52, the counterbore offers a cost‑effective solution without compromising on durability or precision.

Usage

This counterbore excels in environments where precision and reliability are paramount. It is ideally suited for aircraft maintenance bays, aerospace manufacturing floors, and repair shops that service both commercial and military aircraft. The reduced shank design allows the tool to be employed on machines with limited spindle clearance, such as older drill presses or compact CNC units that are still in active service. Its carbide tip is capable of handling a variety of aerospace alloys, including aluminum, titanium, and high‑strength steel, making it a versatile choice for diverse material requirements.

When used with a pilot hole of 1/8″, the tool provides excellent guidance, reducing the risk of misalignment and ensuring that the final counterbore is concentric with the original hole. This is critical for applications where fastener placement must be exact, such as installing avionics racks, mounting engine components, or creating access points for wiring harnesses. The set screw feature allows technicians to lock a pilot or drill bit in place, offering additional stability during high‑torque operations and preventing tool slippage that could damage delicate aircraft structures.

Operators appreciate the tool’s ergonomic design, which minimizes hand strain during manual setups and enables quick changes between different counterbore sizes. The lightweight nature of the tool, combined with its robust construction, ensures that it can withstand the rigors of daily use in high‑volume production environments while maintaining consistent performance over thousands of cycles.

FAQ

What pilot hole size should I use with this counterbore?

The recommended pilot hole diameter is 1/8″. Using this size ensures proper guidance and concentricity, which is essential for precise counterboring and spotfacing in aerospace applications.

Can this tool be used on titanium alloys?

Yes. The carbide tip is designed to handle a range of aerospace materials, including titanium, aluminum, and high‑strength steels. Adjust cutting speeds according to the material’s machinability guidelines for optimal results.

How do I secure a pilot or drill bit in the tool?

The counterbore includes a set screw that tightens against the pilot or drill bit, locking it firmly in place. This feature prevents slippage and maintains alignment during operation.

Is the reduced shank compatible with standard CNC machines?

Absolutely. The 1/4″ shank is compatible with most CNC spindle chucks and manual drill presses, especially those that cannot accommodate larger shank diameters. It expands the range of machines you can use without requiring additional adapters.

What is the minimum counterbore diameter this tool can achieve?

Because the tool relies on a pilot hole, the minimum achievable counterbore diameter is .156″. This limitation ensures the tool maintains structural integrity while providing precise, small‑diameter counterbores when needed.
