High Performance Spotting Drill 5Pcs AlTiN Coated 3/16″ Shank by UH

Description

Product Overview

The UH High Performance Spotting Drill set includes five solid carbide bits engineered for demanding machining tasks. Each bit measures 3/16″ shank diameter, 3/4″ flute length, and a total overall length of 2 inches, providing a compact profile that fits a wide range of drill chucks and collet systems. The 90° tip geometry delivers precise spot drilling, while the two‑flute design optimizes chip evacuation and reduces heat buildup during high‑speed operation. A premium AlTiN (Aluminum Titanium Nitride) coating envelops the cutting edges, dramatically increasing wear resistance and extending tool life when cutting harder materials or operating under elevated temperatures. Solid carbide construction offers superior hardness and rigidity compared with high‑speed steel or cobalt alloys, allowing the bits to maintain sharpness and dimensional stability even at the higher spindle speeds typical of modern CNC machines. The set is packaged in a compact, protective case that keeps the bits organized and ready for immediate use on the shop floor.

Usage

These spotting drills are designed for general‑purpose milling across a variety of medium‑hard substrates. Whether you are working with carbon steel, alloy steel, brass, iron, or non‑ferrous alloys, the AlTiN coating ensures consistent performance and reduced tool wear. The 90° tip is ideal for creating precise pilot holes that guide larger end‑mills or reamers, improving overall dimensional accuracy and reducing the risk of workpiece deformation. The two‑flute configuration facilitates efficient chip removal, making the bits well‑suited for high‑speed machining environments such as CNC milling centers, manual drill presses, and handheld power drills. Users ranging from professional machinists in aerospace and automotive manufacturing to hobbyist fabricators in home workshops will find the set valuable for tasks like creating registration holes, aligning components, and preparing surfaces for subsequent machining operations. The compact size and lightweight design (approximately 2.72 ounces per set) also make the bits easy to carry in tool belts or portable toolboxes for on‑site repairs and field work.

FAQ

What materials can these spotting drills effectively cut?

The bits are optimized for medium‑hard materials such as carbon steel, alloy steel, brass, iron, and most non‑ferrous alloys. The AlTiN coating also allows occasional use on harder alloys when higher spindle speeds are required.

How does the AlTiN coating improve performance?

AlTiN forms a hard, oxidation‑resistant layer on the cutting edge that maintains sharpness at elevated temperatures, reduces friction, and extends the interval between tool changes compared with uncoated carbide bits.

Can these drills be used in CNC machines?

Yes, the 3/16″ shank diameter and 2‑flute design are compatible with standard CNC spindle chucks and collet systems, making them suitable for both manual and automated machining applications.

What is the recommended spindle speed for these bits?

For most steel and brass applications, a spindle speed between 2,500 and 4,000 RPM provides optimal cutting efficiency while preserving tool life. Adjust speed based on material hardness and machine capabilities.

Do you offer replacement bits if one becomes damaged?

UH provides a warranty that covers manufacturing defects. If a bit fails due to a defect, contact our support team for a replacement. Wear from normal use is not covered, but the durable AlTiN coating helps minimize wear over the life of the tool.
