KEO 34182 Carbide NC Spot Drill 1/8″ Dia 82° Angle 1.5″ Length

Description

Product Overview

The KEO 34182 carbide NC spot drill is engineered for high‑precision metalworking where clean, accurately placed holes are essential. Constructed from premium tungsten carbide, the drill tip maintains sharpness even after thousands of high‑speed penetrations, reducing the need for frequent re‑sharpening. Its 82° cutting angle is optimized to produce a smooth entry and exit profile, minimizing burr formation on hardened steel, stainless steel, and alloy substrates. With a compact 1.5‑inch overall length and a 1/8‑inch (0.125 in) diameter shank, the tool fits easily into standard drill chucks and offers excellent rigidity for consistent performance. The NC (non‑countersink) design eliminates the need for additional countersink tools, streamlining the workflow for machinists, fabricators, and hobbyists alike. Detailed specifications list a product dimension of 2 × 0.5 × 0.5 inches and a lightweight 0.64 oz mass, making it easy to handle during extended production runs. Since its introduction in 2014, the KEO 34182 has earned a solid reputation reflected in a 5‑star rating from eight verified customers, and it ranks among the top spot drill bits in the industrial category on major e‑commerce platforms.
The drill’s geometry is the result of extensive testing in both automotive and aerospace applications, where tolerance‑critical components demand flawless hole placement. Its robust construction also resists wear from abrasive materials, extending tool life and delivering cost‑effective performance over the long term. The tip’s heat‑treated carbide reaches a hardness of approximately 1,500 HV, providing superior wear resistance compared with conventional high‑speed steel alternatives. KEO’s quality assurance process includes laser‑guided dimensional verification, ensuring each unit meets the tight tolerance of ±0.001 in for diameter and angle. This precision translates directly into reduced setup time and higher first‑pass yield for production environments.

Usage

Designed for versatility, the KEO 34182 spot drill excels in a variety of settings, from high‑volume manufacturing lines to small‑shop prototyping stations. It is particularly well‑suited for creating pilot holes for welding, fastening, and precision machining of gear shafts, valve bodies, and turbine components. The 82° angle allows the tool to start on a wide range of surface finishes, including polished, matte, or lightly coated metals, without slipping. Operators can employ the drill in CNC machines, manual drill presses, or handheld power drills, provided the spindle speed is matched to the material hardness—typically 2,000 to 3,500 RPM for steel and up to 5,000 RPM for softer alloys. The compact length reduces the risk of chip binding in tight cavities, while the carbide tip ensures clean, burr‑free holes that require little to no secondary deburring.
In addition to industrial applications, the drill serves hobbyists building custom fixtures, model aircraft, and automotive modifications where precise spot holes improve assembly strength and alignment. Safety guidelines recommend using appropriate eye protection, securing workpieces firmly, and applying cutting fluid to reduce heat buildup. For optimal results, maintain a steady feed rate and avoid excessive pressure that could overload the carbide tip. Regular inspection of the tip for wear or chipping will prolong service life and maintain hole quality across diverse projects.

FAQ

What materials can the KEO 34182 spot drill handle?

It is designed for hardened steel, stainless steel, aluminum alloys, brass, and other common engineering metals. Adjust spindle speed according to material hardness for optimal results.

How do I maintain the carbide tip for longest life?

Keep the tip clean of metal swarf, avoid excessive feed pressure, and use proper coolant. Periodically inspect for wear and replace if the cutting edge becomes rounded.

Can this drill be used in CNC machines?

Yes, the 1/8‑inch shank fits standard CNC spindle chucks, and the tool’s geometry is compatible with automated drilling cycles when appropriate feed and speed parameters are set.

What is the warranty coverage for this product?

KEO offers a limited lifetime warranty against manufacturing defects, and the support team will provide a replacement or repair if the tool fails under normal usage conditions.

Is coolant required when using this spot drill?

While the carbide tip can operate dry for short runs, using a suitable cutting fluid extends tool life, reduces heat, and improves hole finish, especially on harder alloys.
