Twist drill bit Smart for metal HSS 14.0 mm x 108/160 mm 1 pc

HSS twist drill bit Smart for metal with a 14.0 mm cutting diameter and overall/working lengths of 160/108 mm, designed for drilling steel and a variety of other metals. This single-piece high-speed steel (HSS) drill bit is compatible with standard drill chucks and can be used in handheld drills as well as drill presses. The geometry and material provide reliable cutting performance for through holes and depth-limited drilling in metalworking and maintenance tasks.

Advantages

The HSS material offers good hardness and heat resistance for metal drilling, maintaining edge integrity at moderate cutting speeds. A 14.0 mm diameter gives a standardized hole size for fittings and fasteners, while the overall and working lengths (160/108 mm) provide adequate reach for most sheet metal and light plate applications. The single-piece construction reduces the risk of breakage at joints and ensures consistent concentricity when used in standard chucks.

Suitable for

• Drilling holes in mild and alloy steels
• Fabrication and assembly of metal components
• Maintenance, repair and retrofitting tasks
• Handheld drilling and drill-press operations

Key specifications

• Cutting diameter: 14.0 mm
• Overall length: 160 mm
• Working length (flute length): 108 mm
• Material: High-speed steel (HSS)
• Design: Twist (spiral) point geometry for metal
• Compatibility: Standard drill chucks

How to use

Secure the drill bit firmly in the drill chuck, ensuring proper alignment and concentricity. Mark the drilling point and, where appropriate, use a center punch to prevent walking. Select a suitable cutting speed and feed for the metal being drilled, apply steady pressure and use cutting lubricant for steels to reduce heat and improve tool life. Clear chips regularly and back the bit out periodically when drilling deep holes to avoid clogging.

Usage recommendations

For best results when drilling steel, use moderate spindle speeds and light to medium feed rates. Apply cutting fluid to extend bit life and improve hole finish. When drilling thin or sheet materials, support the workpiece to prevent deformation and use a backing piece to reduce burr formation on exit.
