Drill bit for metal Smart 18.0 mm HSS, length 130/191 mm, single piece

Solid HSS drill bit for metal Smart 18.0 mm, overall length 191 mm and working length 130 mm, supplied as a single piece. The high-speed steel (HSS) material and standard 118° point geometry make this drill suitable for cutting and drilling a variety of ferrous and non-ferrous metals in workshop and industrial settings. The shank and flute design are intended for use with hand-held drills and drill presses when correct speeds and coolant or cutting fluid are applied.

Advantages

This Smart HSS drill bit offers wear-resistant cutting performance characteristic of high-speed steel. The solid one-piece construction provides good concentricity and rigidity for accurate holemaking. The combination of the specified diameter and working length balances reach and stability, making it practical for through-holes and moderate-depth holes in metal components. The geometry supports reliable chip evacuation when used with appropriate coolant or lubricant.

Suitable for

• Drilling holes in mild steel, stainless steel, aluminum and other non-ferrous metals
• Workshop and repair tasks using hand-held drills
• Drill-press operations for production or prototype work

Key specifications

• Diameter: 18.0 mm
• Overall length: 191 mm
• Working (flute) length: 130 mm
• Point angle: 118° (standard for metal drilling)
• Supply format: single piece

How to use

Secure the drill bit in a suitable chuck and ensure it is properly tightened. Select a drill speed appropriate for the workpiece material — lower speeds for stainless steel, higher speeds for aluminum — and apply cutting fluid or coolant to reduce heat and prolong tool life. Start drilling with light feed to establish the hole, then increase feed to maintain steady chip formation. Clear chips frequently and back the bit out periodically on deeper holes to avoid clogging of the flutes.

Usage recommendations

For best results, use moderate cutting speeds, steady feed, and a suitable cutting fluid. Inspect the bit for wear before use and replace when edge wear or chipping affects hole quality. When drilling thin or delicate workpieces, consider backing material to prevent burrs or distortion.
