Narwhal 3/8in Cobalt Drill Bits (M35) – 3 Pack, 5in Length for Metal & Stainless Steel

Premium Narwhal 3/8 in Cobalt Drill Bits Set

Meet a reliable trio designed for metalworking projects where precision matters. The Narwhal 3/8 in cobalt drill bits are built from M35 cobalt alloy with 5% cobalt content, delivering enhanced hardness and heat resistance for repeated drilling tasks. Expect a durable edge that stays sharp longer as you tackle metal surfaces from stainless steel to hardened alloys.

Each bit is fully ground for consistent diameter control, and the 135° split point helps you start holes with less wandering in harder materials. With a flute length of 3-1/4 in and a total length of 5 in, you’ll experience a balanced cutting action and a comfortable reach for mid size projects, whether you’re working on automotive parts, fabrications, or DIY metal builds.
