SGS 68693 | 4.5mm Diameter x 4.5mm Shank x 24.0mm LOC x 58.0mm OAL 2 Flute AlTiN Coated Screw Machine Length Drill Bit

Description

The SGS 68693 4.5mm drill bit is made for short-length precision drilling where repeatable hole quality matters. This SGS 68693 AlTiN drill bit uses a micrograin substrate with an AlTiN coating to extend tool life and resist heat during high-speed operations. With a 4.5mm cutting diameter and 4.5mm shank, the bit ensures consistent gripping and concentricity in screw-machine and CNC collets. The 24.0mm length of cut (LOC) balances reach and rigidity for minimal deflection in thin-wall and small-part work. A 58.0mm overall length provides the compact screw machine length preferred for automated production and tight-fixture setups. Its two-flute spiral geometry and 27° helix angle promote efficient chip evacuation even in interrupted cuts. The 145° point angle reduces walking and improves centering on pre-drilled starts and pilot holes. A cleared length of 18.1mm aids chip clearance near the shank and simplifies pecking cycles in deep micro-operations. The AlTiN-coated micrograin drill retains hardness at elevated temperatures, making it suited for ferrous and non-ferrous alloys. A shank length of 35.2 mm gives ample clamping engagement for stable drive and repeatable finishes. The right-hand cutting direction matches common machining setups and tooling libraries in production shops. As a screw machine length metric drill, the SGS 68693 is optimized for high-throughput environments requiring low tool-change downtime. The bright, precise geometry and tight manufacturing tolerances ensure predictable hole size and surface integrity. Choose the SGS 68693 4.5mm drill bit when you need a compact, durable, and accurate solution for short-length precision drilling tasks.
