Cobra Carbide 54048 5xD High Perf Non-Coolant Drill 5.10mm

SKU CH-Q9CZ-H1CJB

A 5×D high-performance solid-carbide drill without internal coolant channels, 5.10 mm diameter (0.2010 in)

  • 5xD reach drills deeper holes in one pass
  • Non-coolant design simplifies setup on any machine
  • 10 mm diameter matches precise metric specs
  • Decimal equivalent .2010 eases imperial conversion
  • Cobra Carbide construction resists wear in tough materials

Cobra Carbide 54048 5xD Drill

The Cobra Carbide 54048 is a 5xD high-performance drill bit designed for non-coolant applications. It suits machinists and maintenance teams needing a solid-carbide tool for general-purpose drilling in steel, cast iron and non-ferrous alloys. The 5.10 mm diameter matches common metric tap sizes.

Check shank fit and machine rigidity

Verify that your tool holder accepts the straight shank and that the spindle run-out is within tolerance for a 5xD length-to-diameter ratio. Ensure the workpiece clamping can resist thrust forces without vibration. Confirm the material being drilled is compatible with non-coolant cutting parameters.

Sustained load performance

Under continuous drilling the flute geometry evacuates chips efficiently to reduce heat build-up at the cutting edges. The carbide substrate maintains hardness at elevated temperatures, preserving hole size and surface finish over long production runs. The non-coolant design relies on effective chip removal rather than flood cooling.

Questions about this item

What is included with the Cobra Carbide 54048 5.10 mm drill and what must be purchased separately?

The box contains the 5xD high-performance non-coolant drill itself. A compatible drill chuck or collet, cutting fluid and workpiece clamping are not included and must be sourced separately.

How do I decide between the metric 5.10 mm size and the decimal 0.2010 inch equivalent?

Choose the 5.10 mm designation when your drawings or tap charts are metric; choose 0.2010 inch when working to imperial specifications. Both refer to the same cutting diameter.

What does the 5xD rating mean when the drill is used in a machine?

It indicates the flute length allows a single-pass hole depth of five times the 5.10 mm diameter without needing to retract for chip clearing.
