2D drilling
Short production holes where rigidity, diameter and chip evacuation support a stable cycle.
PRODUCT CATEGORY · INDEXABLE U DRILLS
Indexable U Drill Supplier for 2D–5D CNC Drilling
Select an indexable U drill by finished diameter, depth-to-diameter ratio, insert system, coolant access and machine capability. BOFA publishes the body and insert paths so a quote can be checked before purchase.
SERIES BY DECISION
Choose the family,
then confirm the fit.
Steel, stainless steel, cast iron and other workpieces covered by the selected insert grade and chart. Every model link below leads to a published BOFA page or a technical guide.
3D–5D drilling
Deeper holes require the correct body, insert grade, internal coolant and a verified machine setup.
Hole quality
State diameter, tolerance, blind or through hole, entry surface, depth and burr or finish requirement.
Insert matching
The tool body and WC, SP, WCMX or WCMT insert family must be confirmed as a pair.
QUOTE-READY CHECKLIST
Make the RFQ
easy to compare.
These fields help BOFA separate a standard series from a non-standard requirement. Do not leave the machine interface or critical tolerance implicit.
- Finished hole diameter, tolerance and depth-to-diameter ratio
- Body model, insert designation and grade
- Through or blind hole, entry condition and internal coolant
- Spindle interface, power, quantity and target delivery
FAQ
Before you
place an order.
Use these answers as a starting point; the exact model chart and the actual machine setup remain the final reference.
How do I choose between a 2D and 5D U drill?
Use the finished hole depth, machine rigidity, coolant access and required cycle. The nominal 2D–5D label is a depth option, not a substitute for the body and insert chart.
Why must the U drill insert be matched to the body?
Seat geometry, cutting edge position and chip control are designed as a system. Confirm the body model and insert designation before ordering.
What hole data should I send for a quote?
Send finished diameter and tolerance, depth, blind or through condition, material and hardness, machine interface, coolant method, quantity and drawing.
NEXT STEP
Need a model, drawing or quantity break?
Send the product family, application data and target delivery. BOFA will confirm the available configuration.
