Cylindrical Drill Bit Smart 5×85/50 – Smart brand, Ø5 mm, length 85 mm, working length 50 mm

Cylindrical Drill Bit Smart 5×85/50 is a general-purpose Ø5 mm drill designed for making precise through and blind holes in metal, wood and similar materials. The bit has a total length of 85 mm and a working length of 50 mm with a straight cylindrical shank suitable for hand drills and drill presses. Its dimensions and geometry deliver reliable centering and consistent hole diameter for assembly, mounting and DIY tasks where a defined working length is required.

Advantages

The drill bit combines a compact Ø5 mm cutting tip with a 50 mm working length to reach into recessed areas while keeping tool setup simple. The cylindrical shank ensures stable clamping in standard chucks and reduces runout during drilling. Its moderate overall length provides good balance between reach and stiffness, making it suitable for repeatable holes with predictable diameter and depth control.

Suitable for

• Drilling holes in metal sheets and thin plates
• Creating pilot and clearance holes in wood and soft composites
• Assembly and mounting tasks requiring defined hole depth
• Use with hand drills and small drill presses

Key specifications

• Diameter: 5 mm
• Total length: 85 mm
• Working length: 50 mm
• Shank type: cylindrical
• Intended materials: metal and wood (general-purpose)

How to use

Secure the workpiece and select an appropriate cutting speed for the material being drilled. Clamp the cylindrical shank firmly in the drill chuck to minimize runout. Mark the drilling point, start drilling at low speed to establish a center, then increase speed as appropriate while applying steady, even pressure. Withdraw the bit periodically when drilling deep holes to clear chips and reduce heat build-up. Use cutting fluid or coolant when drilling harder metals to extend bit life.

Usage recommendations

For best results, match drill speed and feed to the material: lower speeds for metals with light cutting fluid, higher speeds for wood. Inspect the bit regularly for wear or chipping and replace when the cutting edge no longer produces clean holes. Always wear appropriate eye and hand protection while drilling.
