Grizzly Industrial Drill Bit Extender Review

Let’s Talk About Grizzly Industrial Drill Bit Extender

The Grizzly Industrial Drill Bit Extender promises a simple solution to a common problem: reaching those hard-to-access areas with your existing drill bits. As a seasoned outdoor and tactical gear specialist, I often find myself needing to modify or repair equipment in confined spaces, whether it’s inside a vehicle, under a sink in a backcountry cabin, or deep within the workings of a complex machine. This extender, from Grizzly Industrial, boasts the ability to add 5 inches of reach to your 3/8″ or 3/8″ stepped drill bits, supposedly without the need for a chuck or facing attachment.

What drew me to this product was the promise of simplifying those tight-spot drilling scenarios. I’ve often resorted to using longer, specialized drill bits, which can be expensive and take up valuable space in my tool bag. The Grizzly Industrial Drill Bit Extender offered a potential cost-effective and space-saving solution, if it delivered on its claims.

Upon unboxing, the extender felt solid, though undeniably simple. The build quality appeared adequate, with two set screws designed to lock the drill bit in place. It felt heavier than expected, a sign of potentially durable materials, but also a potential drawback in already awkward drilling situations. Compared to dedicated long-reach drill bits or flexible extension shafts, the Grizzly Industrial Drill Bit Extender seems to prioritize simplicity and direct power transfer. I chose this over a flexible shaft because I needed something that would be able to handle drilling in more difficult materials and not lose power or flex.

My first impression was cautiously optimistic. The design seemed straightforward enough, but I was eager to see if the set screws would truly provide a secure grip on the drill bits, and if the extender would introduce any wobble or vibration during use. I was hoping it would be the compact, effective solution I needed.

Real-World Testing: Putting Grizzly Industrial Drill Bit Extender to the Test

First Use Experience

My first test of the Grizzly Industrial Drill Bit Extender was during a field repair of a metal storage container hinge that had broken at my hunting cabin. The hinge was recessed, making it difficult to access with a standard drill. I used the extender with a 3/8″ steel drill bit to create a pilot hole for a new screw.

The performance was mixed. The extender did allow me to reach the recessed hinge, but I immediately noticed a slight wobble. This made it difficult to maintain a straight drilling angle. The set screws, despite being tightened firmly, seemed to allow for some play, especially when encountering resistance. I was drilling in a fairly dry environment at 40 degrees, so the elements didn’t play a role.

The wobble took some getting used to. I had to apply extra pressure and focus to keep the drill bit from wandering, which increased the time it took to drill the pilot hole. I was very glad that I was using a center punch to keep the bit from walking even more.

Extended Use & Reliability

After several weeks of use on various projects, the Grizzly Industrial Drill Bit Extender is showing some wear, primarily around the set screw holes. The metal is soft enough that the set screws have started to create small indentations, potentially compromising their grip over time.

Durability is a concern. While the extender itself hasn’t broken, the set screws seem to be the weak point. One set screw stripped after about 20 uses. Maintenance is simple – just wiping it down after use.

Compared to using dedicated long-reach drill bits, the Grizzly Industrial Drill Bit Extender falls short in terms of precision and stability. However, it does offer a more compact and affordable alternative for occasional use in less demanding situations. It doesn’t outperform long drill bits, but it doesn’t disappoint as long as it is used in the correct situations.

Breaking Down the Features of Grizzly Industrial Drill Bit Extender

Specifications

• The Grizzly Industrial Drill Bit Extender accepts 3/8″ and 3/8″ stepped drill bits. This limits its compatibility to a specific range of bit sizes.
• It provides a 5-inch length increase, allowing you to reach into confined spaces. This is its primary function and defining feature.
• The extender utilizes two set screws to secure the drill bit in place. These screws are critical for maintaining a stable connection, but are also a potential point of failure.
• It claims to eliminate the need for a chuck or facing attachment. This simplifies the setup process and reduces the overall length of the tool, allowing for more access.
• The materials aren’t specified, but the extender appears to be made of steel or a similar metal alloy. The quality of the metal directly impacts its durability and resistance to wear.

These specifications are important because they dictate the tool’s capabilities and limitations. The 3/8″ bit limitation restricts its use with larger or smaller drill bits. The 5-inch extension determines how far it can reach. The set screw design influences its stability and reliability.

Performance & Functionality

The Grizzly Industrial Drill Bit Extender performs adequately in providing extended reach, but its stability is questionable. The wobble introduced by the set screw design reduces accuracy.

Its strength lies in its simplicity and compact size. The main weakness is the potential for slippage and vibration, especially when drilling harder materials. It does meet expectations for basic reach extension, but falls short in terms of precision.

Design & Ergonomics

The Grizzly Industrial Drill Bit Extender features a straightforward, cylindrical design. The build quality is acceptable, but not exceptional.

The weight is noticeable, and could make it awkward to use in certain positions. There is almost no learning curve as the design is intuitive, but controlling the wobble requires practice.

Durability & Maintenance

The extender should last a reasonable amount of time with careful use. The set screws are likely the first components to fail.

Maintenance is minimal, requiring only occasional cleaning. Repairing the set screw threads could be difficult, potentially requiring replacement of the entire unit.

Accessories and Customization Options

The Grizzly Industrial Drill Bit Extender does not come with any accessories. There are no customization options available, as it is a simple, single-purpose tool.

It is compatible with any standard 3/8″ or 3/8″ stepped drill bit from any brand. There are no other compatible accessories beyond drill bits.

Who Should Buy Grizzly Industrial Drill Bit Extender?

The Grizzly Industrial Drill Bit Extender is perfect for hobbyists, DIY enthusiasts, and homeowners who occasionally need to drill in hard-to-reach areas and don’t require high precision. It’s a useful addition to a general-purpose toolkit.

Those who require precise drilling, such as professional machinists or carpenters, should skip this product. They should invest in high-quality, dedicated long-reach drill bits.

A must-have modification would be higher-quality set screws made from a hardened steel.

Conclusion on Grizzly Industrial Drill Bit Extender

The Grizzly Industrial Drill Bit Extender offers a simple, affordable solution for extending the reach of your drill bits. However, it comes with compromises in terms of stability and precision.

The price of $37.56 is reasonable for what it offers, but the lack of durability is a concern. The cost may be justified if it will only be used sparingly.

I would recommend it with reservations. It’s a handy tool for occasional use in non-critical applications. I would suggest potential buyers weigh the cost savings against the potential for frustration. If you need precision, look elsewhere, but for quick and dirty fixes in tight spots, it might just do the trick.
