YUEARN M6 Tap & 5mm Cobalt Drill High Speed Steel for

Description

Product Overview

The YUEARN M6 x 1 (1/4″) metric thread tap paired with a 5.0mm (0.2″) M35 cobalt drill bit forms a compact, high‑performance metalworking set. Both components are forged from HSS 6542 steel and receive a titanium coating that enhances hardness, sharpness retention, and corrosion resistance. The tap features a precision spiral point design that efficiently evacuates chips, reducing the risk of breakage during threading. The drill bit’s M35 cobalt alloy excels in drilling stainless steel, cast iron, and other tough alloys without overheating, delivering clean, round holes even under heavy use. Package dimensions are 3.74 x 2.44 x 0.47 inches, weighing just 1.45 ounces, making the set portable for on‑site work.

Usage

Designed for professional machinists, automotive technicians, and dedicated DIY enthusiasts, this set excels in a variety of environments. Use the drill bit to start holes in hardened metals before tapping with the M6 thread tap to create precise, durable threads for bolts and machine screws. The tools are compatible with standard drill presses, bench lathes, and hand‑tap wrenches, allowing seamless integration into existing workshops. Ideal applications include engine repair, metal fabrication, equipment maintenance, and custom fabrication projects where reliable threading and drilling are critical.

FAQ

Can this tap be used on plastic materials?

Yes, the spiral point design works well on plastic, providing clean threads without causing cracks or deformation.

What is the recommended cutting speed for the cobalt drill bit?

For stainless steel, a cutting speed of 15–20 surface feet per minute (SFM) is ideal to prevent overheating while maintaining efficiency.

Is the titanium coating prone to chipping?

The coating is applied to the steel substrate and is highly resistant to chipping under normal use. Proper handling and avoiding excessive lateral forces will preserve the coating.

Do I need a special tap holder?

A standard tap wrench or a drill press with a tap holder works perfectly. Ensure the tap is aligned straight to avoid cross‑threading.

How do I maintain the drill bit’s sharpness?

After use, clean the bit with a brush and light oil to prevent rust. Store in a dry environment and avoid prolonged exposure to moisture.
