Steelex Plus Cobalt Drill Bit Review

Let’s Dive into Steelex Plus Cobalt Drill Bit

The Steelex Plus Cobalt Drill Bit promises to be a workhorse for those of us constantly battling high-tensile steels and stubborn alloys. This drill bit, with its 135-degree split point, aims to make drilling into tough materials less of a wrestling match and more of a controlled operation.

I was spurred to test this particular bit after a recent experience fabricating roll cage supports for my off-road rig. I kept burning through standard high-speed steel bits, leaving me frustrated and behind schedule. The promise of Cobalt Alloy’s superior heat resistance and edge retention was too tempting to ignore.

My initial impression upon receiving the Steelex Plus Cobalt Drill Bit was positive, noting its clean flutes and sharply defined point. It felt solid, not flimsy, and had a reassuring weight. This hinted at a durable construction capable of withstanding the rigors I planned to put it through.

Compared to standard High-Speed Steel (HSS) bits, the Steelex Plus Cobalt Drill Bit immediately stood out due to its color and claimed material composition. While HSS bits can often struggle with hardened steel, the Cobalt infused alloy suggests a tougher, more heat-resistant tool. I also own a set of Titanium-coated bits, but their coating wears off quickly. Cobalt’s material is integrated into the bit, so I expect far better longevity.

I was cautiously optimistic, hoping this drill bit could live up to the hype and save me time and money in the long run. I was eager to see if it truly could handle the abuse I typically inflict on drill bits.

Real-World Testing: Putting Steelex Plus Cobalt Drill Bit to the Test

First Use Experience

I first put the Steelex Plus Cobalt Drill Bit to work drilling through a piece of 1/4-inch thick A36 steel. This is the standard steel used for most general fabrication projects in my shop. I used a variable-speed drill press, ensuring I kept the speed relatively low to prevent overheating.

The bit bit into the steel quickly and cleanly, requiring minimal pressure. I was using cutting oil, but noticed very little heat build-up. The 135-degree split point lived up to its promise, preventing the bit from “walking” across the surface before starting the hole.

There were no immediate issues after the first use. The bit still looked sharp, and there were no visible signs of wear or chipping. I was impressed with the clean hole and minimal effort required.

Extended Use & Reliability

After several weeks of regular use, the Steelex Plus Cobalt Drill Bit continued to perform admirably. I’ve used it to drill through various types of steel, including thicker sections and even some hardened steel components. It performed consistently well, maintaining its edge and requiring less pressure compared to standard bits.

There are some minor signs of wear, such as slight discoloration near the tip. However, the cutting edges remained sharp and effective. I clean the bit with a wire brush after each use and apply a light coat of oil to prevent rust. I expect it to continue to perform well for a long time, given proper care.

Compared to my previous experiences with HSS bits, the Steelex Plus Cobalt Drill Bit is a clear winner in terms of durability and performance. I used to go through several HSS bits for the same amount of work, constantly having to resharpen or replace them. The Steelex Plus Cobalt Drill Bit saves me time and money by lasting longer and performing better.

Breaking Down the Features of Steelex Plus Cobalt Drill Bit

Specifications

• Material: Cobalt Alloy. This provides superior heat resistance and edge retention compared to standard High-Speed Steel (HSS) bits.
• Point Angle: 135-degree Split Point. This design is self-centering, reduces walking, and requires less thrust to initiate drilling.
• Application: Designed for drilling into high-tensile steels and hard-to-machine alloys. This includes hardened steel, stainless steel, and cast iron.
• Intended Use: Ideal for use in portable drills and drill presses. The split point design reduces the torque required for drilling, which is helpful with hand-held drills.
• Price: $8.95. The affordable price makes it an accessible option for hobbyists and professionals.

These specifications are critical because they directly impact the bit’s ability to drill effectively and efficiently into hard materials without premature wear or breakage. The Cobalt Alloy addresses heat build-up while the 135-degree split point ensures accurate starting and reduces the need for pilot holes.

Performance & Functionality

The Steelex Plus Cobalt Drill Bit performs its job exceptionally well, drilling clean and accurate holes in tough materials with minimal effort. Its ability to maintain its edge sharpness significantly reduces drilling time and improves the overall quality of the work.

The primary strength of this bit is its ability to drill through hardened steel without overheating or dulling quickly. Its main weakness is that it is a single bit, meaning you need to purchase multiple sizes for various projects. It exceeds my expectations based on the cost.

Design & Ergonomics

The Steelex Plus Cobalt Drill Bit features a standard twist drill design with a 135-degree split point. The design is optimized for efficient chip evacuation and reduced friction, contributing to its smooth drilling performance.

The bit is easy to use, requiring no special training or techniques. Its self-centering design makes it user-friendly even for those with limited drilling experience.

Durability & Maintenance

The Cobalt Alloy construction of the Steelex Plus Cobalt Drill Bit provides excellent durability, allowing it to withstand the rigors of drilling into hard materials. With proper care, it should last significantly longer than standard HSS bits.

Maintenance is simple: clean the bit with a wire brush after each use and apply a light coat of oil to prevent rust. Sharpening may be required eventually, but the Cobalt Alloy allows for more resharpening than typical bits.

Accessories and Customization Options

The Steelex Plus Cobalt Drill Bit is a standalone tool, not requiring any specific accessories for its primary function. It’s compatible with any standard drill chuck, making it universally usable.

There are no customization options available for the drill bit itself, however, you can utilize various cutting oils to extend its life and improve drilling performance. Different drill speeds may be optimal for different materials, therefore drill speed controllers may also be considered accessories.
