VALYRIANTOOL 5PCS M35 Cobalt Left-Hand Drill Bits Set – Remove Stubborn Bolts & Stubs

Meet the VALYRIANTOOL COBALT STUBBY LEFT HAND DRILL BIT set, crafted for tough fasteners and tight spaces. Built from M35 cobalt steel, these bits deliver durability and steady performance across metalworking tasks. The left-hand twist design is intended to help when reverse drilling is required to coax stubborn bolts or screws free, offering a practical option in challenging scenarios without overpromising results.

Key design features include a compact stub length that reaches into cramped areas. Each bit measures from 2-1/4" to 3-5/8" in length, enabling access where longer tools can’t reach. The 135° split point plus a multi-flute tip promotes self-centering and faster cutting, helping you start cleanly and drill efficiently in tricky materials. This combination is well-suited to stainless steel and other hardened metals, making the set versatile for a range of projects.

The set shines in practical use: removing damaged stubs, bolts, and screws; or drilling a pilot hole for a screw extractor when needed. The included sizes cover common fasteners, and the packaging keeps everything organized for quick selection on busy days.

What you get in the box is a sturdy plastic case that keeps all five imperial sizes clearly visible and easy to grab: 1/8", 5/32", 3/16", 1/4", and 19/64". The compact container makes it simple to transport between jobs and maintain a tidy workshop.

Quick usage guide (optional): prepare the area with light lubrication, center the bolt or screw, apply reverse drilling with the left-hand bit, and switch to an extractor if needed. This approach may improve your odds in stubborn scenarios while keeping expectations realistic.
