Buying Guide for 1/16-1/2 Ultra Dex Set Jobber Length 135

Understanding the Basics

When I first looked into drill bit sets, I wanted to understand what “1/16-1/2 Ultra Dex Set Jobber Length 135” meant. The numbers indicate the size range of the drill bits, from 1/16 inch up to 1/2 inch. “Ultra Dex” typically refers to a high-quality steel or coating that improves durability. “Jobber length” means the drill bits are of a standard length, balancing reach and rigidity. The “135” usually describes the drill point angle, which affects how the bit cuts into material.

Why Size Range Matters to Me

Having a set that ranges from 1/16 to 1/2 inch covers a wide variety of drilling tasks. This range suits everything from small precision holes to larger openings. For my projects, this versatility means I don’t need multiple sets, saving space and cost. Make sure the size range matches your typical drilling needs.

Importance of Jobber Length

I appreciate jobber length bits because they provide a good balance between length and strength. They are long enough for most standard drilling applications but not so long that they flex or break easily. If you need to drill deep holes, longer bits might be necessary, but for general use, jobber length is ideal.

Material and Coating Considerations

The “Ultra Dex” designation suggests a special steel or coating, which enhances performance. From my experience, bits made from high-speed steel (HSS) or coated with titanium or black oxide last longer and resist heat better. This means cleaner holes and less frequent replacements. Consider the materials and coatings based on the materials you’ll be drilling into.

Drill Point Angle – Why 135 Degrees?

The 135-degree point angle is a common choice for tougher materials. I found that this angle helps reduce walking on hard surfaces and improves precision. If you often drill metal or hardwood, this angle is beneficial. For softer materials, a 118-degree point might suffice, but 135 degrees offers better durability and control.

Compatibility With Your Drill

Before buying, I checked that the shank size of the bits fits my drill chuck. Most jobber length bits have standard round shanks compatible with most drills. However, some sets offer reduced shanks or hex shanks for quick changes. Ensure your drill can securely hold the bits to avoid slippage during use.

Storage and Organization

A set that comes with a sturdy case helps me keep everything organized and prevents loss. Look for sets with labeled cases that securely hold each bit in place. This makes it easier to find the right size quickly and keeps the bits protected.

Price vs. Quality

When I purchased my set, I balanced cost with quality. Higher quality bits may cost more upfront but save money in the long run due to durability and performance. Avoid very cheap sets as they tend to wear out quickly or break, especially if you use them frequently or on hard materials.

Final Thoughts

Choosing a 1/16-1/2 Ultra Dex Set Jobber Length 135 drill bit set means investing in versatile, durable tools suitable for a wide range of projects. By considering size range, material, length, point angle, and storage, I ensured my set met my needs and delivered reliable performance every time.
