L. Dewitt's SKU #: 0401L | Mfr Part #: 0401LAccurate holes begin before the drill is fully engaged. YG-1 NC spotting drills help shops solve drill walking, poor hole location, inconsistent starts, burr-prone chamfers, and wasted setup time before drilling by creating a controlled spot, chamfer, or starting feature that helps the next drill enter on location.
- CNC machinists and programmers setting up accurate drill starts, chamfer starts, and spot locations.
- Production teams trying to reduce drill walk, scrap risk, and rework from poor hole location.
- Tool crib and purchasing teams replacing NC spotting drill SKUs by EDP, diameter, point angle, substrate, and length.
- Job shops and MRO buyers standardizing spotting tools for steel, stainless, cast iron, aluminum, and mixed-material work.
0401L: YG-1 0401L 8% Cobalt 90 Degree NC Spotting Drill 5/8 x 1.575 x 4.53 is a 90 Degree NC spotting drill used for general-purpose NC spotting and drill-start preparation. Use this model when the setup needs accurate location, controlled entry geometry, and a clear replacement path from quote to spindle.
Why This Model
Choose this NC spotting drill when the operation needs a reliable starting feature before drilling. The point angle, diameter, flute length, overall length, and substrate should be matched to the following drill, work material, holder rigidity, and programmed feed so the spot supports location accuracy without creating an oversized or brittle entry condition.

What This Solves
- More accurate starts. Spotting creates a controlled entry point so the following drill is less likely to wander.
- Cleaner setup decisions. Angle, diameter, length, and substrate are organized for quick comparison before the job is loaded.
- Better drilling workflow. A matched spotting tool can reduce rework, location drift, and avoidable tool-change delays.
- Results after use. Shops should see faster setup starts, easier drill guidance, fewer wandering drills, and a more repeatable starting point for secondary drilling.
Common Applications
- General-purpose nc spotting and drill-start preparation
- Steel, cast iron, stainless steel, toolroom materials, and general-purpose shop work
- CNC machining centers, toolroom work, production drilling, maintenance machining, and repeat replacement programs
- Spotting before twist drills, carbide drills, short-hole drilling, chamfer starts, and precision hole-location workflows
