1/4″ Carbide Spotting Drills ProDrill 2-1/2″ Length 120° AlTiN Coated

Description

Product Overview

The 1/4″ carbide spotting drill from ProDrill is engineered for high‑precision spot drilling in a variety of materials, including steel, aluminum, and hardwoods. With a total length of 2‑1/2 inches and a 3/4″ flute length, the tool provides ample reach while maintaining a compact profile for tight workspaces. The 120 degree tip geometry creates a clean, accurate pilot hole that guides larger drill bits and reduces material deformation. The shank diameter of 1/4″ matches standard drill chucks, ensuring a secure fit and minimizing run‑out during high‑speed operation.

The drill is coated with AlTiN (aluminum titanium nitride), a premium ceramic coating that delivers a hardness exceeding 3000 HV, excellent wear resistance, and thermal stability up to 900°C. This coating reduces friction, extends tool life, and maintains dimensional stability even under demanding cutting conditions. The carbide substrate offers superior rigidity and edge retention compared with high‑speed steel, making the drill ideal for repetitive production environments and occasional field use.

Usage

Designed for both professional machinists and serious hobbyists, this spotting drill excels in applications such as creating pilot holes for bolts, screws, and larger drill bits, as well as precision work on CNC machines and manual drill presses. Its compact size allows for use in confined spaces, while the robust AlTiN coating ensures consistent performance when drilling at high RPMs. Whether you are assembling automotive components, fabricating metal brackets, or working on cabinetry, the 1/4″ carbide spotting drill delivers reliable results.

The tool’s two‑flute design promotes efficient chip evacuation, reducing heat buildup and preventing clogging during extended drilling sessions. Its balanced weight of just 1.2 ounces minimizes operator fatigue, enabling long‑duration use without sacrificing accuracy. Pair the drill with a variable‑speed drill for optimal control over feed rate and spindle speed, adapting to the specific material and thickness you are working with.

FAQ

What materials can this spotting drill handle?

The drill is suitable for drilling pilot holes in steel, stainless steel, aluminum, brass, and hardwoods. Its carbide core and AlTiN coating allow it to maintain sharpness and resist wear across a wide range of material hardness.

Can I use this drill in a CNC machine?

Yes, the 1/4″ shank is compatible with standard CNC spindle chucks. The tool’s rigid carbide construction and precise tip geometry make it ideal for automated spot‑drilling applications where repeatability is critical.

How does the AlTiN coating improve performance?

AlTiN provides a hard, low‑friction surface that reduces heat generation and extends the cutting edge life. This coating also offers oxidation resistance at elevated temperatures, allowing the drill to operate at higher speeds without losing its cutting efficiency.

What is the recommended spindle speed for this drill?

For most metal applications, a spindle speed of 2,500–3,500 RPM works well. For softer materials like aluminum or wood, you can increase the speed up to 5,000 RPM while maintaining a steady feed rate to avoid chatter.

Is there a warranty or return policy?

ProDrill offers a one‑year limited warranty covering manufacturing defects. If you receive a damaged or defective item, contact our support team within 30 days for a replacement or refund.
