120° Carbide Spotting Drill Colton 3/8″ x 1-1/4″ LOC 3″ OAL

Description

Product Overview

The 120° Carbide Spotting Drill from Colton is engineered for the most demanding metalworking applications. CNC ground in the United States, the drill features a premium sub‑micrograin solid carbide shank that delivers unmatched rigidity and wear resistance when cutting through hardened steel, stainless steel, titanium, and a wide range of other difficult‑to‑machine alloys. The CCT‑1 high performance coating further reduces friction, extends tool life, and maintains a consistently smooth cutting action even under high temperature conditions. With a 2‑flute right‑hand design, a 3/8″ diameter, a 1‑1/4″ length of cut (LOC), and a 3″ overall length (OAL), this spotting drill provides the perfect balance of reach, stiffness, and chip evacuation for precise spot‑drilling operations. The tool is sized to fit standard collet chucks and is compatible with most CNC spindle systems as well as manual drill presses, making it a versatile addition to any industrial or scientific toolkit.

Usage

Designed for both automated CNC machining centers and hand‑held drilling rigs, this spotting drill excels in applications where exact hole placement and minimal burr formation are critical. It is ideally suited for aerospace component fabrication, automotive engine block machining, medical device manufacturing, and any scenario that requires a clean, accurately positioned pilot hole before a larger drill or reamer is employed. The 120° point geometry concentrates cutting forces, allowing the tool to start on hard surfaces without wandering, while the CCT‑1 coating ensures consistent performance across thousands of strokes. Whether you are producing prototype parts in a small workshop or running high‑volume production lines in a large manufacturing plant, the drill’s robust construction and precise tolerances deliver reliable results day after day.

FAQ

What materials can this drill handle?

The drill is optimized for steel, stainless steel, titanium, and other high‑strength alloys, making it suitable for aerospace, automotive, and medical applications where material hardness is a concern.

Is the drill compatible with standard CNC machines?

Yes, the 3/8″ diameter and 1‑1/4″ LOC fit standard collet chucks and can be used in most CNC spindle systems as well as manual drill presses.

How does the CCT‑1 coating improve performance?

CCT‑1 reduces friction and heat buildup at the cutting edge, which helps maintain sharpness, lowers wear rates, and provides smoother cutting even at high speeds.

What warranty or support does Colton provide?

Colton offers a limited warranty against manufacturing defects, along with dedicated technical assistance and a rapid replacement program for qualified customers.

Can this drill be used for spot‑drilling before larger drills?

Absolutely. Its precise 120° point and robust construction make it ideal for creating pilot holes that guide larger drill bits or reamers, ensuring alignment and reducing material stress.
