Klein Tools QRST11 Step Drill Bit | Quick Release Spiral, 7/8–1-1/8 in, Hex Shank, Multi-Material

Overview

The Klein Tools QRST11 Step Drill Bit is built to move through metal, wood, plastic, and aluminum with controlled efficiency. Its dual spiral flutes actively pull the bit forward, reducing hesitation and helping you maintain a steady drilling cadence. The aluminum titanium nitride coating delivers a hard-wearing surface designed for longer bit life, especially under demanding workloads, compared with traditional finishes.

Designed for speed and reliability, this bit features a secure 1/4-inch hex shank that works with both impact drivers and standard drills. The quick-release mechanism enables fast tool changes, while the fast-start tip helps prevent walking at engagement. Readable laser markings indicate two hole sizes, so you can identify the correct setting at a glance and keep your workflow uninterrupted.
