PCB Drill Bit uxcell 1.05mm Micro Set Spiral Flute Tungsten Carbide

Description

Product Overview

The uxcell 1.05mm PCB drill bits are engineered from premium tungsten carbide, a material renowned for its exceptional hardness, wear resistance, and ability to maintain a sharp cutting edge even after prolonged use. Each bit incorporates a precisely machined spiral flute that efficiently evacuates chips, reduces heat buildup, and ensures a smooth, burr‑free hole in delicate substrates such as printed circuit boards, thin metal sheets, and high‑performance plastics. The straight shank design, with a 3.175 mm (0.125 in) diameter, provides a secure fit in standard drill chucks, while the overall length of 38 mm (1.5 in) offers optimal reach for both surface‑mount and through‑hole applications.

Beyond the core material advantages, the bits feature a polished silver finish that not only enhances visual identification but also contributes to reduced friction during operation, extending tool life and delivering consistent performance across a wide range of drilling speeds. The set includes ten individual bits, each calibrated to a cutting depth of 10 mm (0.39 in), allowing users to achieve precise depth control without the need for additional accessories. All bits are packaged in a compact, impact‑resistant plastic case that safeguards the tips from accidental damage and provides an organized storage solution for workshop or field environments.

Designed with both professional engineers and dedicated hobbyists in mind, these micro drill bits meet the stringent requirements of modern electronics manufacturing, rapid prototyping, and repair work. The combination of high‑grade carbide, spiral flute geometry, and ergonomic packaging makes this set a reliable choice for anyone seeking accuracy, durability, and ease of use in micro‑drilling tasks.

Usage

These 1.05 mm drill bits excel in a variety of real‑world scenarios where precision and surface integrity are paramount. In electronics assembly, they enable the creation of clean vias and component mounting holes on densely packed PCBs, minimizing the risk of delamination or trace damage. For hobbyist projects, the bits are ideal for crafting custom enclosures, modifying hobby‑grade drones, or fabricating intricate mechanical parts from acrylic, polycarbonate, and other engineering plastics.

In industrial settings, the bits are frequently employed for prototyping thin‑walled metal components, such as brackets or heat‑sink fins, where a small diameter hole is required without compromising structural strength. Their ability to maintain a sharp edge through multiple drilling cycles reduces tool changes and downtime, making them a cost‑effective solution for low‑volume production runs. The included protective case also facilitates on‑site use, allowing technicians to carry the complete set to field locations for quick repairs or modifications.

FAQ

What materials can these 1.05 mm bits drill effectively?

The bits are optimized for printed circuit boards, acrylic, polycarbonate, fiberglass‑reinforced plastics, and thin metal sheets such as aluminum or brass. Their carbide tip and spiral flute allow clean holes with minimal burrs across these substrates.

Can I use these bits with a standard cordless drill?

Yes. The 3.175 mm (0.125 in) straight shank is compatible with most 1/4‑inch drill chucks found on cordless and corded drills. For best results, operate at moderate speeds (500–1500 RPM) and use proper lubrication when drilling metal.

How do I maintain the sharpness of the drill bits?

To preserve edge integrity, avoid excessive feed pressure and keep the drill speed within the recommended range for the material being cut. After use, clean the bits with a soft brush to remove debris, and store them in the supplied case to protect the tips from impact.

Is the protective case suitable for travel?

The case is made from high‑impact polymer and features a secure latch, making it ideal for transporting the set between workstations, labs, or field locations. It safeguards the bits from accidental drops and keeps them organized for quick access.

What warranty does uxcell provide for these drill bits?

uxcell offers a limited one‑year warranty covering manufacturing defects. If a bit fails due to material or workmanship issues within this period, the company will replace it or provide a refund, subject to proof of purchase.
