Jefe Hex LLC is an American cutting tool company with professionals in cutting tool design and production. As a global industrial technology leader, Jefe Hex has strived to deliver productivity to customers through material science, tool design and wear-resistant solutions. The company has dedicated to provide a steady stream of advanced solutions for both industrial and DIY customers.

Offering a range of high-quality products, Jefe Hex's cutting tools are designed to enhance productivity and efficiency. The square chuck of their wrench centers drives tap without spinning, providing a secure method of drilling the proper hole size before tapping. The straight flute collects chips in the flute, making it convenient to cut both through and blind holes. Additionally, the strong cutting teeth reduce tooth collapsing and offer longer cutting life.

Jefe Hex's product offerings include: - 13 Pcs HSS Three-Flat Drill Bit Set - 9 Pcs Hex Shank Drill Bit Set - 13 Pcs Hex Shank Drill Bit Set - 5 Pcs Hex Shank Drill Bit Set - 115 Pcs Cobalt Drill Bit Set - 13 Pcs Bi-Metal Hole Saw Set

These drill bit sets feature a variety of specifications, catering to different applications and materials. The drill bits are heat-treated and have a black oxide finish, which provides superior durability, high hardness, and corrosion resistance. The 135-degree split point and twist design prevent the bits from walking and allow them to penetrate hard materials without a pilot hole.

In addition to the drill bit sets, Jefe Hex also offers a Drill, Tap and Ratchet Tap Wrench Set. This set includes 9 drill bits in various wire gauge and inch sizes, as well as 9 hand taps covering a range of UNC and UNF thread sizes. The set also includes a ratchet tap wrench that fits 0-1/4" taps, allowing for efficient tapping in narrow spaces.

The tap and tap wrench in this set are designed to make shallow cuts in narrow spaces, making them suitable for industrial production, maintenance, or portable drilling jobs in metal, aluminum, and plastics. The fully ground cutting teeth, big rake angle, and wide straight flute taps offer more accurate threads on both through holes and blind holes compared to rolled or machined threads. They also keep the tap cutting teeth sharper and allow chips to collect in the flutes, enabling deeper hole cutting.

With a focus on quality, durability, and versatility, Jefe Hex's cutting tools have received positive customer reviews, with an average rating of 4.5 out of 5 stars across multiple product lines.
