Industrial HSS and cobalt drill-bit ranges for metalworking, organized by material grade, standard and length series.
We help your brand build a reliable HSS drill bit product line with practical grades, marketable sizes, stable quality, and packaging ready for your buyers.
Position as a broad HSS drill bit collection page for B2B buyers building complete metal drilling assortments. Related buyer terms: HSS drill bit supplier, high speed steel drill bits, HSS twist drill manufacturer, metal drill bit factory, DIN338 HSS drill bits, OEM HSS drill bits.
Review the Selection Guide →Each product option remains connected to its corresponding record so buyers can build a controlled assortment.
General-length range for industrial distribution. Buyers should confirm DIN series and point form before this option enters the assortment.
Short rigid range for sheet and CNC work. Buyers should confirm flute and overall length before this option enters the assortment.
Reach-led range for deep or obstructed holes. Buyers should confirm usable flute length before this option enters the assortment.
Assortment range for retail-wholesale programs. Buyers should confirm increments and replacement sizes before this option enters the assortment.
Select HSS twist drills by material designation, DIN or length series, point geometry and shank. Cobalt content is an alloy specification; a titanium-coloured surface is not proof of a cobalt grade. Confirm the complete combination for each size before approving a mixed assortment.

|---|---|---|
| 3.0 | 33 | 61 |
| 5.0 | 52 | 86 |
| 8.0 | 75 | 117 |

Catalogue dimensional reference. Reference catalogue combinations; material, finish, shank and current availability confirmed per quotation.
Do not approve an HSS assortment by diameter alone: length series, point and shank can differ.
Send DIN & Size ListStart with the workpiece and customer task, then define specifications, packaging and OEM scope.
Separate the hss drill bits range by HSS grade. Keep each material or geometry claim on the exact SKU rather than extending it to every visible variant.
Build the hss drill bits diameter list by SKU instead of giving only a minimum and maximum. The mix separates core sizes, project additions and replacement stock.
State the usable DIN length series needed from hss drill bits at the workpiece. Nominal length alone does not resolve clearance, rigidity or accessory fit.
Separate the hss drill bits range by point geometry. Keep each material or geometry claim on the exact SKU rather than extending it to every visible variant.
Separate the hss drill bits range by flute form. Keep each material or geometry claim on the exact SKU rather than extending it to every visible variant.
For hss drill bits, identify both sides of the shank: machine or holder, then tool or accessory. Similar appearance does not establish interchangeability.

Industrial HSS and cobalt drill-bit ranges for metalworking, organized by material grade, standard and length series.
For metalworking distribution, buyers use hss drill bits on steel sheet, profiles and general parts for general-purpose twist drilling with an application-matched HSS series. Their RFQ should state workpiece, hardness condition and machine.
For machine-shop supply, buyers use hss drill bits on fixtures and production components for replenishing controlled diameters and length series. Their RFQ should send DIN series and quantity by size.
For private-label drill sets, buyers use hss drill bits on professional drill assortments for combining useful increments in indexed packaging. Their RFQ should confirm included sizes, labels and refill plan.

HSS identifies a material family, not one hardness, manufacturing route or universal workpiece claim.
Compare range positions by HSS grade, diameter, DIN length series, point geometry.
Compare for My Program →Review steel and blank identification, flute and point formation, heat-treatment and final marking only against the selected product family and item record.
Request item-specific evidence for steel and blank identification, flute and point formation, heat-treatment and final marking.
Request Factory Information →Build the inspection scope around soft cutting edge, diameter variation, excessive runout, point asymmetry. The quotation should identify which records apply to the selected hss drill bits SKU instead of assuming one acceptance plan for the whole range.
Review cutting-edge condition and the applicable material or joining evidence for hss drill bits; acceptance depends on the confirmed construction.
Check the geometry that can change hole or cut accuracy for hss drill bits; record the agreed measurement method and item-level result.

Send DIN & Size List →First freeze HSS grade, diameter, DIN length series, point geometry, flute form for each hss drill bits SKU.
Then coordinate hss drill bits logo, product marking, labels, carton, case or set composition for the destination channel.
No. Finish and alloy grade describe different layers. Specify M35 or M42 explicitly and request an item-linked grade record.
No. Shank, holder, material, geometry and machine capacity must match. SDS interfaces and ordinary drill chucks serve different systems; check the exact product and machine rather than the word drill.
The manufacturing route is one part of a drill specification. Steel grade, point geometry, dimensions, surface condition and the operation also influence the result. Compare the finished drills on the same workpiece and hole requirement. A “fully ground” label by itself does not establish a particular hole tolerance, cutting life or application rating.
Keep M35 and M42 on separate item lines and retain the DIN series, diameter, flute length, overall length, point and shank for each. A shared finish is not a shared material specification.
Do not approve an HSS assortment by diameter alone: length series, point and shank can differ.
Send DIN & Size List →Identify the base steel grade separately from any coating or finish, then retain the grade with the drill dimensions, point geometry and shank. Colour alone does not identify the material.
No. Flute length, overall length, point preparation and shank can differ even when the cutting diameter matches.
Send HSS grade, diameter, DIN length series, point geometry, flute form, shank, quantities and current references for a product-specific quotation.
