#40 90° Angle Drill Long Drill Bit

Official catalogue country of origin: USA.

YA409-40L — #40 90° Angle Drill Long Drill Bit. Make holes using the stated cutting diameter and shank format.

Applications and industries

Fabrication, machinery assembly and maintenance workshops may need this type of bit for compatible materials.

• Match the bit shank to the chuck and confirm the required hole size.
• Then check reach, point geometry and the maker’s material guidance.

These industry examples are selection guidance, not additional manufacturer approvals.

• Type: 2-1/8" Long Bit
• Size: #40

Compare diameter, working length and point angle. The term aircraft-length describes a length format; it does not by itself certify an aerospace application.

Similar models to YA409-40L

The table compares the listed model details. These are selection options, not confirmed replacements. Check the differences against your task and existing equipment.

Choosing YA409-40L for the task

Select the cutting or finishing geometry for the material and the surface that needs attention. A drill bit, saw blade, burr, file or abrasive has its own engagement pattern. Length, diameter, tooth form, cut grade and shank or attachment can each affect selection. Begin with the process and the required result, then compare the published tool details. A familiar overall shape does not establish the same cutting behaviour.

Next, check the host tool and the working space. A long cutter needs suitable access and support, while a different shank or blade fitting may require a different holder. Confirm the permitted operating conditions in the complete product instructions. For an assortment, identify the individual shapes or sizes needed before comparing set counts. A replacement consumable should match both the machine interface and the material requirement. Keep process settings separate from the catalogue description unless the manufacturer explicitly specifies them for the intended task.

Planning the workshop application

Define the intended job in practical terms before comparing options. Record the equipment or component involved, the operation to perform and the access available around it. Include the current tool or accessory if this purchase replaces an existing item. That context helps distinguish a size change from a different product function. It also makes the application and industry examples above easier to assess against the actual work.

Understanding the catalogue record

The official listing identifies this model as #40 90° Angle Drill Long Drill Bit. Its catalogue grouping is Specialized Drill Bits / 90° Angle Drill Bits. Use that description to identify the product format, then read the individual specifications for the details that matter to the job. A category describes where the product sits in the range; it is not an additional compatibility approval.

For this record, the available specification labels include Type; Size. Read each value together with its label and unit. A drive size, external dimension and working range describe different things, even if their numbers look similar. If the job requires a value that is not listed, request that detail before ordering instead of estimating it from the photograph.

The catalogue country-of-origin field is USA. This field concerns the listed product origin; it does not identify local inventory, delivery time or the warranty terms of a Vietnam quotation. Confirm those commercial details separately.

Comparing options before ordering

The comparison above names YA409-18L and YA409-316L. Review the displayed differences against the requirement for this job. Begin with function and compatibility, then compare access, configuration and included components. If the names differ by size, drive, colour or kit format, identify which difference matters before making a choice. Similar models are not automatic replacements, and a larger or more expensive option is not necessarily the better match.

Purchase questions and receiving checks

What should the order include?

Ask for a line-item description of the supplied configuration. For a set or kit, confirm the contents; for a component, confirm the quantity and the matching parent model where relevant. If photographs show a larger assembly or several items, do not assume all of them form part of this SKU. Keep any essential accessories and documents explicit in the quotation so that receiving checks can follow the same requirements.

Receiving, care and record keeping

On receipt, compare the item and its packaging with the ordered model, quantity and configuration. Check the supplied components and any requested documentation. Keep the product identification visible in the workshop’s inventory record. If the delivered item differs from the confirmed order, resolve that difference before assigning it to the planned job. This is especially useful when a range contains visually similar sizes or accessories for different parent tools.

For continued use, follow the manufacturer’s instructions for inspection, cleaning, storage and maintenance. Do not assume that a cleaning chemical, lubricant or maintenance method used on another tool is suitable here. Keep damaged or uncertain equipment out of the planned task until its condition is assessed. Record any replacement parts by model so future orders use the confirmed reference rather than a visual guess.

Ordering in Vietnam

Send Techmaster Vietnam the model number YA409-40L and details of your task or existing equipment. Include any required sizes, connections and accessories. This helps identify the correct configuration.

Before ordering, confirm the quotation, lead time, package contents and applicable warranty terms. The official catalogue is the technical reference; it does not establish local stock or a Vietnam selling price.
