LLDSIMEX 13Pc Extension Drill Set - 1/16in to 1/4in (64ths), 6in Long HSS Bits

Overview

Meet the LLDSIMEX 13-piece extension drill set, a compact kit designed for deeper holes with accuracy and control. The set covers sizes from 1/16in up to 1/4in in 64ths, with bits that are six inches long for reach in tight spaces and extended projects. This configuration supports a range of general-purpose drilling tasks, whether you are working on metal, wood, or composite materials in a workshop or at a job site.

Durability and material quality

Durability is a core focus. The bits are crafted from M2 high-speed steel (HSS), chosen for edge retention and long wear. This combination helps you approach projects with steady confidence and fewer tool changes during longer sessions.

Compatibility and setup

The set is designed for versatility in how you work. It is compatible with hand-held manual drills and with portable or stationary machines, allowing you to switch between setups without swapping tools. This makes it a practical choice for both shop environments and on-site tasks.

What you get

What you obtain is a practical, general-purpose deep drilling kit tailored for standard-duty operations. The size range provides options for small-hole work, while the six-inch length offers reach when space is constrained. The kit is packaged in a sturdy metal box for durable storage and easy transport between sites.
